I'm not 100% sure on all the implementation specifics here so I won't
pretend otherwise.

I'd hope that as a blessed kernel implementation that it would be clever
and sensible here, but who knows!

Yeah, so the video quirks should be mostly useless now.

I spoke to some Arch and Fedora folks and they've all had very few
issues with the switch in this regard.

See reply to my upstream question here:

I'm not sure of this one specifically - will try and clarify.

Yeah those kind of ones should just be migrated I think.
