Disclaimer/reminder: I'm an outsider trying to ensure regressions are
handled well, I'm neither affected by the problems nor involved in PCI
subsystem development.

Well, guess so, as regressions and fixes for them iirc have stacked
here, so there might be no good established base to go back to. But
*normally* going back to one is what Linus afaics wants to actually
prevent exactly a back-and-forth or an exchange of one bug for another.
He wants to ensure that people can always feel safe to update. See these
quotes from Linus for details:
https://www.kernel.org/doc/html/latest/process/handling-regressions.html#on-back-and-forth

So yes, not reverting might be the best at this point, as 7.2 is out for
a while already and so far there are only two reports iirc. You folks
are the best to judge here. That's why I'll also leave the other aspects
you raised to others.

Ciao, Thorsten
