I'd suggest doing it now (or soon, before 2.6.40), just to make sure
there aren't massive complaints about performance regressions, etc.,
and then deprecating it at say 2.6.42, and then waiting 6-9 months
before removing it.  But, I'm a bit more conservative about making
such changes.

(Said the person who has reluctantly agreed to keep the minixdf mount
option after we found users when we tried deprecating it.  :-)
