A critical factor allowing Wayland adoption on the desktop is that you can just run an X server as a Wayland client to use applications that are X only. For SF to work on the desktop they would need the same capability.
Symmetry, I am not sure if this is true. In the 1980s I relied on being able to use remote X servers for a lot of my work. But, it has been many years since I have needed to do that. In modern times, SSH, tmux, emacs, Clojure/Ruby repls, etc. just do everything that I need. I like Android a lot, and it might be very good as a general OS for the public and perhaps even for developers.
I was trying to refer to x servers in general, not just remote x servers. I can't remember the last time I used X over a network, but many of the programs I use very day don't use GTK or Qt, and so wouldn't work if I switched over to some windowing system that couldn't run X as a client.
