Using a Request Response in a Mass Transit System?

The first great order command, whatever you want to call it, that that triggers that sargo. The consumer can check and say, hey, is someone waiting on a response for this? And if they are, i'm going to do x, y and z, and then respond to them. Versus, if they aren't waiting for a response, maybe i'll do something different. So having a separate response type for that request response conversation can be useful.
