Making a remote GTK or QT UI is feasible and should not even be hard. AND since in that case only very little data is going to be transmitted, it can actually be useful.

I would think that the toolkits would also be able to use the local D-Bus sessions, ssh-agent sockets, etc. instead of also having to forward those in addition to the X session socket (or just leaving it as-is and always hooking up to the remote one).
You could have automatic gvfs and KIO slaves made for wayland-local:/ and wayland-remote:/ protocols so that the local and the remote filesystems could be accessed. There's a lot more than just pushing pixels across a pipe to get the full experience of running a remote application as if it were local.
