Thx for this.

Not that it matters much, but there is at least one more:

I tend to think this is the right thing to do. But for completeness to
ensure everybody is aware of this: I'm pretty sure (Mario will know for
sure) this will cause a regression for a few users, because a9c4a912b7dc
was meant fixing a regression for them. Not sure how many users this
might affect, but I guess it are at least those linked to in a9c4a912b7dc:

https://bugzilla.kernel.org/show_bug.cgi?id=217406
https://bugzilla.kernel.org/show_bug.cgi?id=217394
I assume that could be avoided by adding quirk entries for their
machines. Some of the tickets have the data to do so.
