How about adding CONFIG_DELETED_THINGS.  If you enable it, you get a
message asking you to speak up if you actually need anything in there.
CONFIG_DELETED_THINGS would default to n, and the new (and temporary)
things under it would also default to n.

Think feature-removal-schedule, but with teeth.
