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. :-)
