It wouldn't matter. If you have the "class-dump" tool, you can use it on the
10.6 or 10.7 AppKit framework. You'll see that most of the Cocoa protocols are
present, but NSApplicationDelegate isn't.

Correct.

I doubt it. It's not that anybody made a conscious decision to omit
NSApplicationDelegate. It's just a consequence of how the code was written and
what the compiler and linker do.

Who knows. It depends entirely on what the AppKit code used and what the
compiler and linker did with that.

Anything which referenced them in the described manner (includes a class which
adopted them or code which references them via @protocol()).
