I'm actually talking about MI *protocol*. I think that usefulness of that
should be judged from the point of view of its intended clients -- that are
frontends, which nowdays means GUI. If MI is protocol specifically designed
for some task, then it should not include some fields just because TUI
needs those fields.

Why can't MI layer weed out unnecessary information?
