Well there hasn't been any interest shown from the global maintainers, but I
think it would be helpful. Do you need any of the annotations that are
not generated by level 3 annotations?  (Specified by

Keeping level 3 allows a transition stage, I would now like to use it for
breakpoints-invalid and frames-invalid as stated above, in case I suddenly
find that Emacs does need them.
