> Inability to scale applications which required xwayland properly or at all

Scaling for wayland applications worked however scaling for xwayland apps absolutely did not. The actual reality is a blurry mess and as you go back further you see more and more apps that only run via xwayland.

Due to the scattered way different features are handled on Wayland nonblurry scaled xwayland apps became or will become available at different times. For instance KDE fixed this issue in 5.26 which became part of Kubuntu with 23.04 released last month. For Debian users this day has not yet come and for many who update their software only infrequently to major releases xwayland apps may take years to become a reality.

That’s more than a bit of a misrepresentation. In practice, people with NVIDIA cards could run Xorg, and could not run Wayland compositors. You can use whatever wordplay you want to pretend otherwise, but Wayland absolutely did not support all the hardware that Xorg on Linux supported.
