Sorry for the confusion. My point is that Wayland does not and has never
required clients to show client side decorations. The only connection is
a rather loose one specified in xdg-shell. In practice, clients and
compositors alike are free to do whatever they want with decorations. We
should not formalize a requirement to behave any particular way. This
just provides a means of communicating each side's preferences.
