Sure. The first instance, if/when it happens, would probably be a trendsetter.

I think it still matters for impending decisions. For example, we're
about to engineer how to backport a sliding window of Python across
the sliding window of backbranch support. Shorter windows tie our
hands less.
But I agree that if that other thread is otherwise settled, we've
effectively declared that RHEL 9 is the minimum for PG20, and that
would make me very happy.
