It is, so I've forked the conversation 😉

Are there other container-specific distros other than Alpine that people
use widely?

I'm guessing the answer is "no," but I'm curious to hear what others think

The discussion of distro-specific wheels has been brought up. I believe
they are technically supported if you have your own index server, but PyPI
doesn't, I believe, to keep an explosion of wheels people can't widely use
down.

Currently, if you want to cover all formats PyPI supports you need to
produce 5 wheels. Adding a musl-based wheel format would bump that to 7 (as
I assume musl supports 23 and 64-bit OSs).

For me, the questions of whether to support musl-based wheels on PyPI is
will there be enough users to justify the cost to all project maintainers
to produce 2 more wheels per release and what would the
manylinux-equivalent spec look like (since it would have to be generic and
not specific to Alpine)?
