@(4) Going forward, here is the problem that concerns me: Wayland withholds many capabilities apps had under X, reserving them for the compositor or extension designers. This would be fine if people could just pick the compositor with the features they need. But you don't get to pick your compositor because your compositor is bound to your DE. Compositors are fragmented, and fragmented in the way that holds back innovation rather than the way that promotes it.
(4, contd) We need *some way* to give people the freedom to replace the compositor out from under the DE if they need a better feature set, so that extension innovation becomes possible. I may about to be say something incorrect, but I believe the problem here is GNOME. I *think* other DEs/WMs are ultimately based on wlroots, so wlroots-based compositors could be drop in replacements. But GNOME's Mutter is way more specialized. IDK how to work around that. We all switch to Cosmic? :(
