I'm hesitant to merge more governors. (We already have too many imo).
The userspace logic for automatically deciding which is the best one to use is
already pretty hairy, so any additional ones at this point would have to be
accompanied with some really compelling reasons why the existing ones can't
be fixed in an acceptable manner.
