Excellent trap, but I won't step in ;-)

I'm not even advocating to start some kind of deprecation cycle. All I
meant to say is that _if_ there's something to be removed, it might
possibly be a good idea to have some kind of "soft-" or "2-stage-"removal
which would provide an opportunity for users to accommodate 
or complain.
