Yes, for platforms for which either there is no way to ask for events indicating that an interface has appeared or disappeared or for which we don't yet get those events. We should also hook this up to the code to get those events on the platforms where we *do* get them (Linux and OS X, currently).
I think in Qt we might want to do that by generating signals when events appear or disappear, and have widgets that display that list connect to those signals. (It's currently done in a somewhat *ad hoc* fashion in GTK+.)
