A solution there would just be to add a similar large chunk of Wine-specific code, which could be an option now if none of the other options work. There is no real other way to do it if the other window systems are going to break the security assumptions in Wayland. Edit: AFAIK the only real reason X11 needs special support is because functionality that would normally be provided by an X window manager needs to be provided by the Wayland compositor, most of the heavy lifting translating the X11 protocol is done out-of-process in XWayland. The amount of code needed there on the Wayland server side is actually not particularly large, I don't know enough about all usages of the Win32 API to say how that compares.
