It is, but I think it's increasingly the case that packages which don't
support Python 3 will either be shamed into it, important enough to get high
quality contributed ports, or will be effectively abandoned and alternatives
found.  This is a big change from where we were several years ago.

All my new $work code is Python 3.  Some libraries are bilingual but
applications start and stay in Python 3-only.

Just recently the last two dependencies in Mailman 3 that blocked us from
beginning the port to Python 3 have been replaced[1].  We have active branches
that are slowly porting own code now[2].

While we can't quite declare victory yet, and there will always be legacy code
for which there just aren't the resources to port, I think it's perfectly
reasonable for Python 3 to be the default target version for any new code (and
a lot of existing code).

Cheers,
-Barry
