As someone that has dealt with PSF and PyPI at a product level for packaging at the intersection of Python and AI for compute hardware, we consider PyPI an immature ecosystem. It's absolutely great for python libraries, but that's it. It's not ready for the flood of AI hardware that is coming. Mojo looks promising, but not sure how it's going to interact with PyPI.

I'm waiting for the day when setuptools and pip are a thing of the past.
