For me it is not great because of the new requirement for "rust" for basic Python. Does not make any sense. Especially if the main selling point is "speed". I never encounter cases where the pip install equivalent was particularly unbearably long except in very badly designed and broken projects. The kind of one that that import every possible dependency (nom style) with pinning things on broken and incompatible set of dependencies... Also, I like very much the concept of one tool for one usage. And having venv and pip is great, having one tool cluster mixing everything is not. Sure in most dummy usage cases it will be great, but you have more chance of clusterfucks and complicated unresolvable issues. Even more if developers are opinionated on a single way to do something.

I'm not sure how much spelunking you did in the core interpreter, but the Astral rust code is much easier to understand and modify.

  But C did not disappear, now you need C and Rust. If Python was based on Rust, I guess I would not mind, but it is not. Also C is also supported everywhere! And personally I don't see why Rust would be more easy to understand than C. C is really straightforward compared to Rust. All of that being said, for something as basic and important as a package manager I would except that it is implemented in pure Python so it might easily be hack, modified or fixed without requiring any compilation... Like most of pip and setup tools were. Just wait for the moment that you can't update some libraries in your code because UV will not work without being updated, but an updated version binary is not available or you need to fix/backport something, so you need to build it. But unfortunately rust devs will not care supported older systems/os, so you are fucked. And you need to upgrade your whole system just to be able to update a simple application library.
