The crux is: how widespread this is. I know you say "TBD", but do you have any estimates? > For an upgraded system to notice this change, it would need to be > already using one of these drivers.

Could we add a runtime warning to those drivers in F35 and F36? (That'd need some patch in the code I assume, but that should be easy to do.) It'd be nice to warn users that their configuration is becoming obsolete. Also, I don't think we want to go from "used" to "removed" directly. I would very much prefer for the code to remain built for F37, but require an opt-in. The can even declare the package as unsupported, "bugs will not be fixed", etc. Inevitably, some users will be caught off guard and unhappy, and if they have *some* workaround to prolong the old state, it'll probably save us all a few grey hair.
