Ah I just assumed y’all did, that actually makes sense now why you hadn’t run into that issue yet :)

It actually makes sense now that I think of it, since the rewheeled pip has worked for us in virtualenv - had we unbundled the bundled code, it would have failed.
For what it’s worth, we do attempt to make it easy for the system level pip to have it’s copies of stuff unbundled, but if you keep it bundled and use rewheel it’ll be easier to do modifications to it than having the system pip and the “bundled” pip have different sources. Because the pip source just bundles stuff as part of it’s source while the venv source has it inside a Wheel so you have to do an unpack, modify, repack dance that rewheel will do for you.

FWIW the technique used by Python for PEP453 matches what we already were doing in the virtualenv package, so if you modify the behavior there, it might be reasonable to also modify it in virtualenv to use rewheel. That would also cut down on the number of different sources of pip.
