Hahaha no. You physically cannot do it. Read PEP-508. Python can install packages from anywhere. Even if you start with PyPI, the dependency can be specified as hosted on a random unrelated resource. And, on principle, I wouldn't pay PyPI anything. I want them gone, I don't want my money to feed a bunch of incompetent people who make my life miserable. So, if they were to implement this idea, I'd be hosting my packages on GitHub or Gitlab etc. and have dependencies link to those sources.
