The software I've heard of that does such things today is perfectly
happy with today's interface level notification.

Equivalently:  it's not free, and we don't know what it'd be good for.

That "small and potentially useful" argument is the essence of
feature creep, which is why I don't like it.  I'd far rather
see some examples of improvements it would enable ... but I
don't think there are any, since it'd be just a subset of what
we can already do without such calls.
