Real time processes can hog the CPU so they're almost orthogonal to a desktop where you want all of it to be reasonably responsive. I suppose there might be situations where you have a visual application, e.g. an oscilloscope, where real time might make sense. But you probably want the application owning the whole display rather than being a client of a desktop with many other clients in contention for the same resources.
