[Python-Dev] Proposing PEP 345 : Metadata for Python Software Packages 1.2

How can they know that they depend on "a quirk in behaviour of an older
version" if a newer version hasn't been released? This sounds bogus.

Besides, not letting me install their app/library on a newer Python just
because they are not /sure/ it will work is IMO an active nuisance. The
user should be treated as an adult.
