Why would that be a short-term fix? It would work for the entire life
time of Python 3, and can be easily extended for Python 4, so it sounds
like a permanent solution to me.

As a permanent solution, you need to keep the problem statement in mind,
though: to allow people to determine whether a package works with Python 3.

Well, the classifiers *are* part of the metadata of the package.
