Sorry for the (relatively) late reply. I was very busy this week.

IIRC I mentioned before that I prefer new eclasses over changing the
existing ones (in absence of a real eclass versioning system).
Actually a good point was raised on -dev ML about using multiple
smaller eclasses, instead of one over-complicated one that tries to do
too much.

I 100% support going for python-r1 and distutils-r1, deprecating the
existing eclasses in use now. We may need to add one or two more new
eclasses, to replace functionality from current python.eclass.
