Yeah that is fine.

It depends? I suppose I'd have to trust the new hw enabling is better
than what is currently in tree for that hw, and doesn't do anything
sneaky like enabling PSR or rc6!

Well this round drm-next was open straight after -rc1 effectively, it
just happened -rc1 was during KS and made it kinda annoying to push
trees. I've based -next on -rc2, but yes I think keeping a tree open
all the time is required.
