@mst in order to participate you have to follow 2 X accounts (and a few other things). Just follow the link to the main contest site.

@meldrik What is the difference in a fake account to a not fake account? You support the fascist in either way. Absolutely not what I stand for.

XDG-decoration is not a core part of Wayland. So there is no guarantee that the compositor your user runs does support this. So the general improvement would at least be that you dont have to test both.¹
On top of that the app could have more control over it's decoration, for accessiblity stuff. Like going in a OLED/e-Ink/High-contrast mode.

@ChristianWS "Design follows technology and vice-versa." Thats a hard one. Yes, and also no. Things dont need to be the same to behave the same. Take Firefox and Chrome. They do not look the same, they still behave the same. They share a common design guideline. You need to go to the settings to see the parts that differ.
If KDE provides a good design guideline devs would follow them, because it's easier and faster to have working patterns instead of putting work into it yourself.
