Well, they could only remove the item if it was *already* the case that
it didn't do anything. In general, I think Peter neglected to address
the question of whether "deprecated" objects/functions/etc still have
their original functionality, and where along the path the replacement
functionality starts to exist. It's certainly a bad idea to be throwing
warnings about something that people still have to use.
