Where do you find Alpine-compatible wheels? Many ones uploaded to PyPI aren't, because e.g. both GitHub actions [0] and Azure pipelines [1] don't have Alpine images. Is it reasonable to expect maintainers of small, open-source libraries to write and maintain their own Alpine runners?

I guess if you know your company's workflow depends on Alpine, you can build and cache them yourself. But the wider community doesn't benefit from that.

Exactly zero packages upload Alpine-compatible wheels to PyPI.

The manylinux specification assumes glibc, so there is no valid distribution format which would allow the publication of non-glibc wheels.

However there is an in-progress PEP to support it: https://www.python.org/dev/peps/pep-0656/
