We actually already have a fair bit of pain to keep yum 3.2 working with
python 2.4 and 2.5.  Things like the integration of cElementTree and
pysqlite both led to API changes that we're carrying compatibility cruft
for.  The former isn't too bad.  The latter regularly makes me want to
stab myself repeatedly in the eyes.  We're not taking advantage of the
new try/except/finally bits which actually hurts quite a bit -- and just
trying to emulate or reimplement it _doesn't_ work nearly as well.

And even if there wasn't _anything_ in the python 2.4 -> 2.5 transition,
that doesn't mean that there hasn't been in the past and won't be in the
future.  Why would we want to tie the hands of a project like that?  And
don't forget -- it's not necessarily just python... it could be anything
else that we depend on.  rpm-python/rpm being high on the list of
probables.
