Debian currently doesn't modify the setup.py.

It is not a policy matter. There might be a problem if the packager has
different interpreters than the installer (package build vs. package
install). I assume python-setup only uses python as interpreter so
everything should be the same as now without the packager changing
anything.

If you could offer a simple way to just create the py.testXX it should
be possible to create them for every interpreter on the installed system
(using the hook in python-setup).

I don't have a strong opinion on this. I would favor skips or a warning.
That would give an easy way to share which interpreters are supported
without caring if they are installed on the specific developer machine.
