I'm not sure an overwhelming majority of Python developers care one way or the other. Like, I'm sure uv is nice, but I've somehow never had an issue with pip or conda, so there's just no reason to futz with uv. Same deal with Jujutsu. It's probably great, but git isn't a problem, so jj isn't a priority.

A majority of HN users might agree with you, but I'd guess that a majority of developers, to paraphrase Don Draper, don't think about it at all.
