Client side decorations are fine, but removing the option of server side decorations from app developers is stupid IMO. KDE and wlroots have this functionality.

Practically, for small apps that don't really have their own style (or games that are just one big opengl window) it's much better to rely on the window manager to provide a titlebar that somewhat fit in with the rest of the system. This is what users expect when coming from Windows or macOS.

Instead, apps like kitty just provide a godawful stopgap titlebar for GNOME users, because implementing good CSD is outside the scope of the project.
