And I very much do not agree with that.
Python 2 must die. If upstream decides to drop python2 support, we should
too,
we should not keep old odd versions indefinitely[1].  This creates chaos
because
we end up with inconsistent mess.

break.

it takes extra steps to do that, but i think it's worth the effort in

What we should do here is to just drop python2 from python-foo, what I'll
do once
the dust after current 3.9 / rpm deps rebuild settles.
