Well, I'm 64 and have been using planes since I was about 9 years old.
The manner in which you state your prejudices is really quite offensive. (I believe in USA quite means very) ~;-)#
There never seem to be any experiments which might give us results to support your opinions.
If you really think "the Hock improvement is very weak" you definitely inhabit cloud cuckoo land.
I published, many years ago, results of an experiment where I planed up an 8 foot by 22 inch European, air dried Beech bench top.
I needed three 1970s Stanley blades to take a finishing pass. (Alan Peters used to sharpen 6 at a time so that he could keep working). A Hock blade got the job done with one sharp blade.
I repeat Hock blades were the best thing to happen to Stanley planes, in the latter half of the 20th century. The 60 1/2 block plane would be another good example.
Generally the people who don't like A2 steel are those who cannot sharpen effectively.
I nearly mentioned James Krenov, but I suspect you don't rate him either.
The English Cabinetmakers of the last century sought infill planes to surface their difficult exotic timbers. These had thick blades, and thick cap irons. Odd eh.

David, what kind of experiment would you like? Preference of professionals in use (historically or otherwise) is about as good as it's going to get. Individual experiments lead to conclusive statements on things like derek has said, where he's had an issue with a stanley cap iron that nobody else has. Or, in the case of planing, a little bit of wax and then the heaviest plane always wins. Experiments don't allow someone to deal with contrary wood or what happens once they've got a significant sweat going. A planing experiment to me is dimensioning 2 board feet of wood with two different planes on separate days and assessing how much effort it took and whether or not the results are acceptable.
Earlier this year, I finish planed a white ash bench surface with a stanley 4 with one sharpening. Of course, I approached it differently than you probably did - I set the plane for a heavy shaving with the cap iron set properly (perhaps it was 4 thousandths), and then I took a couple of passes with a thinner shaving once I had nice continuous heavy shavings (as in, continuous implying that all of the tearout was removed from the ash - something ash is definitely good at - tearing out). The double iron is more important than the hard iron. I don't use 1970s stanley blades, though (I don't like them, either, they are soft AND they leave a gummy wire edge - a bad combination), I use older blades that are plain carbon and that are available inexpensively (well, they are probably oil hardening steel and not "plain carbon" steel, but that's what people refer to now as carbon steel). I have made the comment before that if someone believes their iron is too soft, it's probably because they're not working a thick enough shaving for most of their work. I believe that, but it really doesn't ring a bell if someone is using a plane for finish work and joint fitting only. Carborundum stones existed a century or more ago, and there is nothing that would keep makers from making an iron 62 hardness - the razors were already there, and the steel was relatively clean bessemer process diemaking steel. Even before that, corundum and emery powders were widely available, and are prescribed for carvers. They would've sharpened anything if sprinkled on an oilstone. why is it that the users of planes didn't demand irons of that hardness when they were actually using planes heavily?
Certainly if I'd have taken a lot of thin smoother shavings smoothing my bench, as I have said many times, the modern irons will take more of them in a row. But it is inaccurate, I believe, to assume that someone who was working at rate would've worked that way - it takes several times as long (and much more effort). That is not illuminated until you can safely take a thick jointer or smoother shaving without using a high angle.
I have used everything you describe, I shave with a straight razor, I have never had any problem sharpening effectively. I started out only with alloy steels, and I have vials of diamond powder in my bench down to a tenth of a micron - I've played with it all, and all of it works. It's not a matter of what works, it's a matter of what works best in the context of use. Tenth of a micron diamond is not very useful when you're taking jack shavings, and it's easy to contaminate. Waterstones require care above and beyond taking the lid on and off, and oilstones require only the care of a conscientious sharpener.
I don't know the story about infill planes. They are not that common over here, and i've read on Joel Moskowitz's blog that there was social pressure to purchase them in britain. I have made three of them and have a fourth in process that got set aside strictly because I learned to use the cap iron. Recall when you learned about it (the cap iron) on sawmill creek and said that it was one of the few groundbreaking things you've seen in decades? That was me.
I don't know that much about krenov and his tools because I wouldn't like to have most of the furniture he's made and I don't like laminated planes. When he described planes that have handles as being uncomfortable to use, then I kind of lost interest in his discussions about plane design. He's only working against several centuries of professional users there (and my own experience with mild arthritis and planes without handles)
I don't use a block plane very often, so I can't say much about what's better, but in that situation where there is no second iron to keep a plane in a cut, the modern irons are probably a significant gain. Especially since, in my opinion, a lot of the later stanley block planes are pretty shoddy. I've got two, the older is nicely made (an 18), and the newer is poorly made (a 65).
I state my conclusions plainly because without doing it because if you don't, people literally go back to "everything's equally good" kind of mentality and "I wonder what will be new in the next catalog". Been there and done that. When it turned to sweat to start from rough wood, then you really start to be a lot more critical than that.
I have made the comment to derek several times that talking about things (steels, planes, etc) that are important to have when you go from rough to finish...that kind of talk leaves people who only smooth with their planes behind. There's a whole other world out there beyond shooting boards and smoother shavings. It's one that has rabbet planes instead of shoulder planes, chisels instead of rabbeting block planes and router planes, and on and on.
I don't speak from shaky footing on any of it. If we were talking about furniture, and it went above and beyond relatively plain items, certainly I would be.
