> I'm in favor, assuming that the wheel tags and PyPy backwards
compatibility situation is OK. Can't really find any examples. What I mean
is that for CPython wheels contain tags like "cp27" or "cp35". PyPy wheels
should have tags "pp<something>". Are the PyPy cpyext layer and the
<something> defined such that a new PyPy release won't break older wheels?

Another thing to think about is that 1.12 on pypy won't pass its test suite
(though it's close), and we're not yet testing new PRs on pypy, so no
guarantees about 1.13 yet. I think on balance these probably aren't reasons
*not* to upload wheels, but it's a funny place where we're talking about
providing "official" builds even though it's not an "officially supported
platform". So we will at least want to be clear about that. And someone
will have to handle the bug reports about the test suite failing :-).
