IMHO, it definitely needs to be stated in a very visible place that 
level-2 annotations are deprecated.  But I think it's more important to 
work on what's missing in MI, because it should be clear that as it 
currently stands, MI is not a complete solution to a GDB front end.

I actually tried very hard to convince the gdb-ui developer to use MI 
from day one, but given the lack of support for CLI commands, and the 
fact that no one of the GDB developers stepped forward to add the missing 
features when gdb-ui was still in limbo, I had no alternative but to 
agree that for now, level-2 annotations are the only practical way to go.
