> Python wheels that work on any linux (almost)

So, you're doubling down on OP's misnomer of "cross platform means whatever platforms I use", eh?

I do not know what you are objecting to. I have successfully packaged wheels for MacOS and Ubuntu with manylinux. I presume it works with some others too, but that is what I can personally attest to. Alpine is catered to by the musllinux project.

You should be specific about which distributions you have in mind.
