This has been made to work similarly to X11, requests for the data device contents are notified through GDK_SELECTION_REQUEST events, the data stored in the GDK_SELECTION property as a reaction to that event is then stored into the wayland selection implementation, and written to the fd when requested/available. https://bugzilla.gnome.org/show_bug.cgi?id=697855
