The solution is simply for the maintainers merging the immutable branch
to do that in a branch based on -rc2. Eg. I've rebased rtc-next on -rc2
(fast forward, I didn't have any patch). I can now merge this branch if
necessary, problem solved. If you can't rebased, nothing prevents you
from merging -rc2 in any branch.
