I'm not sure "major versions" is the most correct term here, but I think your point is spot on

For Python, 0.1 increases are major versions and 1.0 increases are cataclysmic shifts.

I don't know about that. For me, f-strings were the last great quality-of-life improvement that I wouldn't want to live without, and those landed in Python 3.6. Everything after that has not really made much of a difference to me.
