I think it makes sense to make the switch before we retire, because
then people's expectations are changed ahead of time and they can
adapt to The Future(TM).
Actually I think it makes more sense that F31 provides no /usr/bin/python. Then
a lot of things which depend on it can be found and fixed since they have not
adapted to the Future any other way.
We've been actively forbidding packagers doing that for more than a year.
Most packages that still require /usr/bin/python are either:
* FTBFS since Fedora 28 (and I will make sure we follow the policy this time
and finally kill those)
or
* willingly workarounded by the packagers who tend to ignore all our
recommendations (nothing we can really do here)
Totally that is 10 runtime dependent packages and 64 buildtime.
If we take away /usr/bin/python and "python" provide, those things won't resolve.
If we change it to Python 3, some of them might work, most of them probably
won't. Some of them are broken already (like

Note that there are packages that actually need any /usr/bin/python to build,
such as gcc. But I wouldn't bother with he buildtime deps much - either they
build with py3 or they won't.
The runtime deps bother me, because they need to be fixed or retired either way.
I'll happily retire them all (with big loud warnings before we do).
