My two cents about this: kernel development is plagued by the unability
to rename and rework things as soon as backward compatibility is
involved. I believe that renaming and reworking things is quite a good
thing to do when it leads to a situation that is easier to understand
and makes more sense.

In this case, I don't see any blockers that would prevent us from doing
this, so I am strongly in favor of it. I really don't see how increased
noise and "historical reasons" make up for better clarity.

Cheers,

Paul
