Which is why we should act on Holger's pre-PEP to drop the rel=""
attributes from projects that don't actually use them -- builds
involving those projects will immediately drop to one HTTP request to
PyPI, plus one to whatever host has the actually needed file.

And that's without any tooling changes whatsoever: builds all over the
planet will just get faster and more secure, right away.
