Unless they want to support applications that use legacy OpenGL calls or develop new applications that use modern desktop GL. There seems to be a dependency issue here that needs resolving. Qtbase itself has a configure time switch for OpenGL ES vs Desktop whereas the QPA plugins can be decided upon at runtime. Is there some way we can move the GL decision to be runtime too I wonder? I don't like how even building the wayland QPA plugin means that we limit Qt and the apps built with it to OpenGL ES. I really don't want to get into a situation where we can build modern OpenGL apps for the desktop that work fine on Windows and Mac but not on Linux just because Qt for Linux has the wayland qpa plugin built.
