In response to Wayland Breaks Your Bad Software
I say that the technical merits are irrelevant because I don’t believe that they’re a major factor any more in most people moving or not moving to Wayland.
With only a slight amount of generalization, none of these people will be moved by Wayland’s technical merits. The energetic people who could be persuaded by technical merits to go through switching desktop environments or in some cases replacing hardware (or accepting limited features) have mostly moved to Wayland already. The people who remain on X are there either because they don’t want to rebuild their desktop environment, they don’t want to do without features and performance they currently have, or their Linux distribution doesn’t think their desktop should switch to Wayland yet.
And don’t forget 1:1 gestures and the Crash-Resilient Wayland Compositing that keep the application alive even tho the “compositor” crash, so it does restart without any data loss.
Edit: forgot to mention the lockscreen protocol, because on xorg if the lockscreen crash then you view the desktop and you have the device unlocked!
