Thank you.  That is _exactly_ what I meant when
I asked (more than once), what was meant by
"commands meant for this specific mode" and
"commands bound to modes".  (I got no answer.)

+1.  That's clear and useful.

(Whether or not such a criterion should filter
by default is another story.  But at least
getting this criterion nailed down would be
a blessing for the discussion.)
