Sure, it's awesome (and has served us well for a very long time), but as hardware and software change, it has placed limitations on how we can compose the logical components of the display server, and can be done separately anyway. Much like X servers on platforms that don't use X as their display server (and available for practically every OS), you will be able to run an X server alongside Wayland, and run X clients against it from anywhere. (Plus you can always run rootless remote clients with other protocols such as RDP.) Wayland may replace the X server that talks directly to your hardware, but it won't replace or discard the utility of network display protocols (X or otherwise).
