While it might be going away soon, I'm also not that bothered about
the small amount of churn that a tidy up patch like this causes,
and it might not go away ;)

However it is rather odd to have a 'reserved' entry for a register.
can't see that providing any useful information.  Normally I'm
happy to have complete register sets as a form of documentation
if the author wants to do it that way.  This however seems silly.

Alex, we haven't really gone with marking things as 'going away'
before.  I'd suggest we take a guess and remove it if you and the
team an analog don't think it's in use.  Happy to get a patch for
that if you want to send one.  Of course, Rodrigo could do that
patch to get started if that works for everyone? :)
