Well then, I don't see a way forward on the issue of helping
distributors to manage version numbers sanely. I don't know of any
operating system package manager that returns different comparison
results depending on what specific letters are used in the version

All this specialness-of-certain-letters may make sense to Python core
developers, but it's just going to result in nonsensical version
progressions as far as operating system distributors are concerned. What
will be the resolution there?
