Cool to see so many peeps on the Fedi!
While I haven’t used uv (been kinda out of Python for a while), and I understand the concerns some have, the Python community getting concerned about good package/project management tooling is certainly a telling “choice” about how much senior Python devs have gotten used to their ecosystem. Somewhat ditto about concern over using a more performant language for fundamental tooling (rather than pursuing the dream of writing everything in Python, which is now surely dead).
So Simon is probably right in saying (in agreement with others):
while the risk of corporate capture for a crucial aspect of the Python packaging and onboarding ecosystem is a legitimate concern, the amount of progress that has been made here in a relatively short time combined with the open license and quality of the underlying code keeps me optimistic that uv will be a net positive for Python overall
Concerns over maintainability should Astral go down may best be served by learning rust and establishing best practices around writing Python tooling in compiled languages to ensure future maintainability and composability.
