We want to keep the wl_surface around, because surfaces create their resources on construct and keep them until destroyed. See the HWND ond Windows and the XWindow on X11. This is relevant for graphics resources, where we want to have access to the VkSurface and eglSurface while the GdkSurface is hidden. We also want these surfaces to be permanent and not change during the lifetime of the GdkSurface. What we can - and must - destroy however are the xdg surfaces, because those handle visibility on screen. And we also need to ensure no buffer is attached, so that during the next creation of the xdg surface we don't get a protocol error.
