You betray your ignorance of wayland

Yeah. If Gtk does that too, most objections to Wayland basically fall away: nobody's likely to implement Wayland-only programs (just as people don't write against raw Xlib these days), and if the toolkits can switch based on an env var or something, the user can choose with whatever granularity is desired between insane blazing performance and remotability (which means I can turn remotability on and forget about Wayland completely).
