Python package management is one of the reasons I can't stand using the language. I'm a self taught developer, and I mostly make specific tools for my coworkers to analyze data and keep track of production manufacturing. When I pick up a language, the last thing I want to do is fight the package manager, especially on distribution. I'm also not fond of how pipenv, an inferior tool to poetry, gets pushed by PyPA seemingly due to the creators involvement with the PSF, but that's just my opinion/speculation.

Rust package manager is good. C# with dotnet cli is by far my favorite set of tools, however I do wish you could publish nuget packages as source libraries.
