One of the major complaints thrown at X11 in the 90s and early 00s was the inconsistent mismatch of UI conventions and behaviours. GNOME and KDE were still at interesting-novelty status, you had OpenLook and Motif apps on the distribution CD with distinctive styles, and every so often you'd load a libXaw program where all the scrollbars were weird and you suddenly used the right mouse button in strange and exotic ways.

How did they manage to get through the project without addressing this point, and make it even worse, by offloading stuff like "screenshots" that was taken as a given to the nonstandardized compositor layer?

I'd also have wanted to see much more of a "one true widget library"-- so Wayland!GTK or Wayland!Qt are just thin wrappers on top, which would ensure you get any native theming or customizability/accessibility tweaks cross all your software for free.
