We're just starting to fully use MI in Emacs and formally parse (Dmitry) the
output but I would think it's possible parse anything in Emacs (Lisp) and it's
just a question of complexity.

I quite like the idea of incrementally changing the output with new commands
because as soon as MI3 is released, you can be sure people will find
shortcomings with that. You could say it is a more agile approach.
