> That feels like cargo-culting the toolchain instead of asking the uncomfortable question: why did it take a greenfield project to give Python the package manager behavior people clearly wanted for the last decade?

This feels like a very unfair take to me. Uv didn’t happen in isolation, and wasn’t the first alternative to pip. It’s built on a lot of hard work by the community to put the standards in place, through the PEP process, that make it possible.

What uv did was to bring it all together.
