With Wayland compositors now being able to start Xwayland on demand, the next logical step is to be able to stop Xwayland when there is no more need for it. The Xserver itself is capable of terminating itself once all X11 clients are gone, yet in a typical full session, there are a number of X11 clients running continuously (e.g. the Xsettings daemon, IBus, etc.). Those always-running clients will prevent the Xserver from terminating, because the actual number of X11 clients will never drop to 0. Worse, the X11 window manager of a Wayland compositor also counts as an X11 client, hence also preventing Xwayland from stopping. Some compositors such as mutter use the XRes extension to query the X11 clients connected, match their PID with the actual executable name and compare those with a list of executables that can be ignored when deciding to kill the Xserver. But that's not just clumsy, it is also racy, because a new X11 client might initiate a connection the X11 server right when the compositor is about to kill it. To solve this issue directly at the Xserver level, this add new entries to the XFixes extension to let the X11 clients themselves specify the disconnect mode they expect. Typically, those X11 daemon clients would specify the disconnect mode XFixesClientDisconnectFlagTerminate to let the Xserver know that they should not be accounted for when checking the remaining clients prior to terminate.
