Beware that -Wdeprecated-implementations is closely akin to
-Wdeprecated-declarations (it's sort of the Objective-C version of
that warning, emitted when you try to implement a deprecated @protocol
method), so you should be careful to keep those two options parallel
in construction. IMO you shouldn't add any special treatment to
-Wdeprecated-declarations that you don't also add to
-Wdeprecated-implementations.

Other than that, this sounds like an excellent plan. Moving the (???)
warnings into -Wdeprecated is certainly overdue, and removing
-Wdeprecated-declarations from -Wdeprecated sounds like a good idea.
