Just because you can't imagine the application that doesn't mean that Richard doesn't have one at hand :)
Apart from that, I don't see any problems with visualizing such an app as well (or at least a normal RT app which got in trouble because of an overloaded rest-of-the-system).

It wouldn't. It would involve copying a bit of existing code to make an RT path and then chainsawing the RT additions from the normal code path. It's an absolutely trivial change.
