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.
Replacing good legacy will always be a struggle. X11 works pretty well and has been stable for decades. Most of the things that suck about it already have workarounds.
The advantages of Wayland are not directly visible for the end user. The security part will be great once it’s completely integrated on the distributions to give granular permissions to software. The simpler apis and greater performance will help libraries creators, but most developers don’t touch X directly and won’t touch Wayland either.
Being stable for a couple of months is not good enough. People will use it once distros trust it enough to make it default, and this will probably only happen once Wayland or its compatibility tools work with most software and major applications work significantly better on it.
