We could of course add such code. But it turns out to be convenient for other reasons to use a separate message. For instance, using a separate message will let us handle the case where DisplayNow put us into accelerated compositing mode. We'll end up sharing quite a bit of code with the existing SetSize/DidSetSize messages.
