You seem to be under the impression that we have difficulty removing
obsolete features when we decide it's time for that.  But the reality
is we do remove such obsolete features.  It's the decision to do so
that's difficult, not the execution of the removal once we do decide.

P.S.  Could you please refrain from using Reply-To in your messages?
It causes emacs-devel to appear twice in the addresses of the
responses, so I have to manually delete one of them.  TIA.
