The root cause is that the manylinux wheels that are currently published are based on glibc, but Alpine is based on musl libc. There is a separate musllinux platform tag that can be used in that case.
Do you think musl-compatible builds could be added? This would improve compatibility with certain distributions like Alphine Linux, Void Linux, and others focusing on size and speed.
