We'd love to get your help testing this -- please try it and comment
here on wheel-builders or in
https://github.com/pypa/warehouse/issues/869 if you see any problems.

And there's an open issue https://github.com/pypa/wheel/issues/231 about
DESCRIPTION.rst in wheels, in case any of you can weigh in there!
