You can find this kind of similar setup in embedded systems (ie. SailfishOS), as X11 makes no sense outside of keyboard+mouse setups, but I don't expect it until a bunch of years for regular desktops (say when X.Org will have died), I'm doing this right now to avoid having to rush to get rid of X11 with having to push the End-of-Life date way back it's upstream date (that happened with python-2 because it wasn't much prepared until the last year or two).<br/>
It's also the kind of setup that I expect soon in security-oriented systems because Wayland addresses a number of design flaws.
