> Do you think there are 22 competing package managers in python because the package/import system "just works"?

There aren't; a large fraction of tools people mention in this context aren't actually package managers and don't try to be package managers. Sometimes people even conflate standards and config files with tools. It's really amazing how much FUD there is around it.

But more importantly, there is no such thing as "the package/import system". Packaging is one thing, and the language's import system is a completely different thing.

And none of that actually bears on the LLM's ability to choose libraries and figure out language syntax and APIs. For that matter, you don't have to let it set up the environment (or change your existing setup) if you don't want to.
