The only time I ever interacted with python packaging was when packaging for nixos. And I can tell you that the whole ecosystem is nuts. You have like ten package managers each with thirty different ways to do things, none of which specify dependencies in a way that can be resolved without manual input because y'all have such glorious ideas as implementing the same interface in different packages and giving each the same name and such. Oh and don't get me started on setup.py making http requests.
