Most people don’t give a shit and just want a system that works. As a lot of distros switch to / have switched to Wayland I have never noticed any issues in daily usage of any of my devices, in fact my surface laptop 4 can’t do external displays if I’m running x11 but that feels like a surface issue not a display manager issue. Point being that the switch is happening and a majority of users do not care as long as their systems keep running, and in my experience there’s no reason to believe they won’t.
Honestly this is one of the only things holding me back from going to graphene. Once this is available to non alpha users I might make the switch properly.
