Carrying multiple versions of python becomes pretty infeasible very quickly. It's easy enough to package just python itself, but any non-trivial user is going to require modules also. So how do you decide which modules to bring in, how to handle the fact that they may have moved on to python 3 only, etc. It's a big huge mess. We'll likely stick with 2.x for a while and watch as python3 matures and fix things up as we can against 2.6+. Once there seems to be a critical mass or compelling reason, we'll get to have a flag day. Yes it will hurt. And for those who also develop things for older distros, yes, they'll probably need to fork off an old-python or whatever branch and probably only do bugfixes for some of those distros. But this is no different from apache 1.x -> 2.x, anyone doing kernel development, or a number of other cases that have occurred over the years.
