>The graphics drivers and Wayland are probably adequate. But absolutely everything from there on up - window mangers, GUI toolkits, applications, configuration tools - needs to be written from scratch Doesn't projects like Enlightenment [1] do just that? They use Wayland and everything else(WM, Applications, libraries) was developed from scratch over it. I had used it on Raspberry Pi 3, it was the smoothest desktop experience I've had on a Pi. But, unfortunately RPi wasn't officially supported and so none of the 3rd party softwares worked. [1]https://www.enlightenment.org https://www.enlightenment.org
