In general, we can start removing python2 support from leaf nodes
first... so a given thing is an app and doesn't have public modules
which other packages use, you can go ahead and drop python2 support.

Similarly for library packages once there are no longer any python2
reverse dependencies, python2 package can be dropped as well. And so

Quite a few apps are python3 "only" already.
