+Subject: [PATCH] libweston: add weston_layer_fini()
+
+Layers did not have a fini sequence before, which means the compositor
+layer list might have stale pointers temporarily when shutting down. A
+bigger problem might be having views linger after the destruction of the
+layer.
+
+These problems were not observed yet, but if they exist, this patch
+should help to find them and then fix them.
+
+The check in weston_compositor_shutdown() is not an assert yet, because
+it will trigger until all components call weston_layer_fini() correctly.
+Some components do not even have a tear-down function to call it from at
+all, like fullscreen-shell.
+
+The same with the check in weston_layer_fini().

+This function here is a wl_resource destructor, but we will need another

+
+Rename the existing function, because the old name fits better the new

+Subject: [PATCH] libweston-desktop: introduce weston_desktop_client_destroy()
+
+This new function is callable explicitly, unlike the old function that
+used to have the same name.
+
+This will be needed when tearing down what
+weston_desktop_xwayland_init() puts up.
+
+Since calling weston_desktop_client_destroy() for an external client
+(one that has a wl_resource for this) is a bug, add asserts to prevent
+it. This will only be needed for the internal client: XWM.
