Was the wood worked mostly green (presumably) and then finished after drying? Who knows. If they can tolerate 60 degrees, it would suggest that speed wasn't much of an issue yet, which is what my comment above is about. To come up with something like that that's extra cost, there would need to be economic motivation for it - which is either profit incentive (to be the early users) or just being able to stay in business economically (the later users).
I haven't got any historical reference for productivity and how it was viewed 3000 years ago. In societies where class division is extreme and there is a lot of subsistence labor, there doesn't seem to have been a real great drive for innovation or efficiency. Just add more people.
I'd speculate that your Roman wood shop owner would have all the rough planing done by slaves (and maybe the fine planing done by skilled slaves). I believe slave labour was pretty cheap (in terms of the Roman economy), so the economic incentive for greater efficiency might not be there. You had to feed your slave, even if there was nothing for him to plane, so giving him a more efficient tool wouldn't be any benefit unless you had more work than your current slaves could handle.
