Didn't think of it earlier, but how about updating python3 (the major-
version symlinks) to 3.8 as a test: release now? That should help
maintainers start the move without breaking the world for everybody
else. Posted this to a branch to help:

Your call, it's still supported upstream for almost 5 more months. I

There's now a 2.7.18, we should probably pick that up, as it has the
final upstream fixes. After that, it's time to start moving to 3.8 en

These are fine as is, but they also don't need to be rebuilt or updated

We don't need to _obsolete or remove python3-* packages, we just
need to track how many don't have python38-* equivalents yet.
Obviously that's still the vast majority, since 3.8 just got updated to
a stable version.
Jon Turney, if a python-foo source package was previously building e.g.
python27-foo, python36-foo, and python37-foo, and now starts building
only python37-foo and python38-foo, is calm going to complain?

There are a lot of _obsolete python-*, python2-*, and python3-*
"packages" which we don't need to count. How many of those names are

This is the last step.
