And yes, I do some Python development myself (not much packaging but “using” Python in the sense of writing Python code). I find the Python experience largely painless: I currently have 2.7.12 and 3.4.5 installed. Eventually 3.5 will get installed and 3.4 will go away. Just like every other package. I won’t need to do any config file editing, just a revdep-rebuild run perhaps. So regardless of the situation for maintainers, as a user, I don’t see this pain.

As another regular user, you most definitely will see this pain if you
need to deviate from your profile defaults for python.
I'm like you - use lots of python, package some, write some. I also
don't go past the current ~arch python-3 because I have a good sense of
what waits for me if I do.
That you and I don't suffer too much breakage at all since years now is
a testament that *someone* is touching all those ebuilds when they need
to be touched, that they are managing to do it without much visible
fallout is a minor engineering miracle or sheer hard work.
I think William has a point; sometimes making a criteria a negative one
result in a lot less work. A good survey usually gives numbers that let
you tell if it will.
