I would like to reiterate the points that many have made thus far.

Existing applications depend on annotate level 1 (ddd, gvd, ...) and 
level 2 (emacs, cgdb).  Until the MI interface is complete (supports 
CLI and GDB user output) and all existing applications have made 
the switch to using the MI, the annotations cannot be removed.  
My current understanding is that GDB/MI is not a completely viable 
alternative for these GDB interfaces to use to replace annotate 1 or 
2.  Therefore, the annotations -- while being deprecated -- must be 
retained in future releases until the GDB/MI is capable of 
supporting these applications.
