There's a function in distlib, distlib.version.legacy_key(), which sorts
compatibly with pkg_resources.parse_version().

I'm not sure I understand this point. Shouldn't that default be "pkg_resources",
given that all the existing distributions on PyPI will work with that scheme and
not have the Version-Scheme present in their metadata?
