Right, I should not have phrased it like this. My fault. I do not think Python interpreters being distributed on PyPI as wheels should be the goal on a technical level, but on a conceptual level I feel like it could be a good thing to aim for, as in it should be as easy as pip-installing wheels from PyPI. I think this argument was already made in the context of Pybi and Posy.
I am wondering a bit if Packaging is the right place for this thread.
