Well, we should be clear, here: the most recent Emacs release uses
only annotation level 1.  It's only a not-yet-released Emacs that has
a just-added mode that uses annotation level 2.  So if GDB were to
delete annotate level 2 today, Emacs would not lose any functionality.
(I am not suggesting that we delete annotation level 2 today, it's
just a rhetorical device.)
