What X needed was to slim down. That's something I can get behind. But the Wayland folks went too far, and the rationale seems to have been "because this is our first real opportunity to break from X"... in other words, because they could. What we needed was an X12, not something different for the sake of being different: evolution, not revolution.

I personally find vnc or NoMachine NX better than X sharing. The main reason for this is that my programs don't quit if my connection goes down. While I do hope for a good remoting system, I'm not sure that 'ssh -Y' is the best way to do it any more.

ssh works out of the box everywhere. I can be connected on as many hosts as I want, launch any graphical application, anywhere and they just display correctly. I can not imagine launching a different X server almost for each application I am running. I have a single X server and often tenth of clients running on three of four different hosts. And when I have to access an "external site", I just phone them, so that they "open" the connection, then I do my ssh -Y and I can launch many GUI running on all their hosts to investigate their issues.

I have NoMachine NX on my home computer. It is very useful, but it is far more heavy weight than a simple ssh with X11 forwarding.

Probably because most unix users just use console ssh or web GUIs for remote access.
