It is still a problem where there are no binaries for platforms otherwise supported by the distro, and in fact supported by the package being built - because uv-build is the only part that does not run on given platform and can't be reliably built for it
I agree that they exist. My 2c: the wheels in that link of manylinux, musl linux, Windows, and MacOS will work on 99.9% of users' OSs.
