I mean, the app can request the compositor to have "server-side decorations" but this is treated as optional protocol.
See https://wayland.app/protocols/xdg-decoration-unstable-v1

It is implemented on all major desktops except Gnome 😭

So now all apps need to implement their own decoration, user resizing, etc feels very backwards and wasteful.

The way some compositors implement some features and some not is a bit annoying, but the main features are well supported overall.

Now to get DPF to support wayland... 😁
