Yeah, that's how it is because it is costly for maintainers to maintain.
What's your point though, is poetry better in this regard or what are you suggesting as a better alternative to uv?
if I was asked to deploy python code? My alternative would probably be crying. Personal deployments? I'd probably go with pip hash installs ideally only of wheels, assuming that this would leave the environment in a reproducible state, probably wouldn't though.
pip has the same problem as uv in this regard, but I'd be hoping that there would be less breaking from breaking changes, due to the amount of people depending on pip not breaking.
If I had money? I'd fork pip or uv and assign some people to make an downstream with extended support.
