I don’t think PyPI has any reason not to add more possible wheel variants,
ultimately it comes down to the authors to decide which variants it makes sense
to support. A MUSL version of manylinux might be very reasonable, or it might
be crazy hard to nail down. I also don’t think there’s any reason we can’t have
a PEP that figured out a standard format for distro specific wheels, and just
let people produce alpine linux specific wheels (authors could just not produce
say, ubuntu specific wheels and say they’re already covered by manyinux, or
they could produce ubuntu specific if they want to rely on apt-get installed C
libraries).
