It's probably a matter of nobody knowing anyones intentions on the internet, story of forever.
For what it's worth with planes inaccurately made, I had an american made plane (those went downhill in terms of cosmetics first) that was obviously cut without any markout. It was a try plane and the front of the mortise was somewhere between 5 and 10 degrees from being perpendicular to the sides of the plane.
I cut it up, but not because of that, just because it was worn out. Of course, it worked fine, but someone was in an extreme hurry making it (and it was a professionally made and marked plane).
In fact, I cut up a lot of planes - an ugly plane with a great iron set over here will sell for pennies. The great iron set, however, wouldn't. What's not common over here is later planes like the mathiesons and griffiths where everything is crisp and the plane was taken care of.
The wonky scroll I take as an exception because it's not what someone would shoot for now if they were hoping to do swift professional quality work. I don't know that much about violins, but from talking to George Wilson a fair amount, I know some of the famous makes went through stations in life where they used subpar materials in their violins. It's either amati or guarneri (or both) who have pictures of their violins floating around with knotty wood.
I'm not looking to do that equivalent, and I'm not looking to spend 30 hours making a plane, either. I'm looking for somewhere in the middle.
You can't tell so much from the picture, but the plane in the back of the two jack planes is one I made for myself. It's not well finished, but, of course, it works well. It's hard to make one that doesn't unless you ignore what's going on when you're making them. You couldn't sell it to someone unless you made up a story about rustic unfinished details or some BS.
