> Public index servers SHOULD NOT allow the use of local version identifiers for uploaded distributions.
I'm thinking this should just say "PyPI" and not "Public" broadly.
The point is for local versions not to confused with the one authoritative upstream version sequence, not that it couldn't be "public".
I can imagine locally versioned distributions needing to be distributed or available "publicly" (e.g. for a specific platform or system).
Considering the recommendation to use the "python.integrator" extension, which is generally about "downstream" modification and redistribution, it seems inconsistent to say that this redistribution couldn't be public.
