The issue has been reopened:

However, they're still going to have a potential compatibility problem
to deal with, since extensions built against a narrow Python build
won't run against a wide one. As such, putting a narrow Python 2.7
build into the build environment and encouraging folks creating Python
2.7 wheels to upload both variants may still be a preferable option.
