So if we just say 

 use_ozone=1 ozone_platform_x11=1

it won't work right? That's unfortunate because all the other platforms work
that way.

That configuration will use ozone-x11. What do you mean by "won't work"?

 use_x11 = is_linux && !use_ozone
+use_x11_backend = use_x11 || (is_linux && use_ozone && use_ozone_x11)
 
 use_ozone_evdev = use_ozone
