Yes, I wouldn't bother with that.  What concerns me more is what Roman
pointed out: some applications rely on getting multiple events
(obviously they aren't using Firefox...), and even as described, the
event will fire less than they might previously have relied on.

I'm not super-concerned about that.  Applications that blindly
renegotiate based on the event aren't going to work particularly well
anyway.  Justin's proposed formulation does address that by ensuring
that dirty (what I think we should call negotiationNeeded) is only
cleared if the session description completely covers the requested set
of channels/tracks.
