They probably need Wayland to bridge/wrap GL or video acceleration to
Wayland. Wayland probably doesn't need GL, because it does use another
GL implementation and hardware video acceleration is probably not
supported by Wayland at all, but maybe requires always Xwayland.

Just guesses. A short research seems to confirm the guess related to
GL. The same short research doesn't provide anything halfway clear
related to hardware video acceleration.
