Comment(by strider72):

 Okay... here's a thought:  Is there a definitive "last" hook in WordPress?
 Right after that fires we could fire off a function that looks at
 did_action and compares it to an array of deprecated hooks, and fires
 _deprecated_filter as needed.

 I was first trying to figure how to hook it after the do_action is called,
 but of course the problem there is that do_action fires even if there are
 no hooks attached to it.

 Would it slow down do_action/apply_filter too much if we simply added an
 in_array to compare $tag to an array of deprecated hooks?
