I thought that Volodya was also adding a type field.

I think it means its generally less likely to make a difference.  In Emacs, I
just take the value of the field amd insert it in the appropriate window at
the appropriate place.  Thats why the type currently gets duplicated in the
locals window.  Removing the type prefix just removes that duplication, I
don't have to make any changes to the lisp code in Emacs.  Adding a field,
however, might break my parser if I'm not expecting it.

However, perhaps you're thinking specifically of Eclipse.

But there have been many changes to mi2, notably adding the fullname field
in several places, since it became the default level.  I'm just suggesting
that we don't have mi4, mi5, mi6 etc because it gets too complicated.
