I imagine this would mean at least that new and updated Portfiles
would specify 3.6 as their default version, and that we would update
old Portfiles that already specify that they can run on python 3.6 to
use that.

This would likely leave a large residue of Portfiles that should be
slowly examined for updates so that within a year or so, they're all
python 3 compatible.

Presumably we would want to fix that. It would not need to be a rush,
of course, since we still have something like two years before 2.7
becomes deprecated, but it would be reasonable to slowly and
deliberately get ourselves there rather than having to rush at the
last moment.
