Comment (by kencu):

 I also ran into software that would check for EGL and use it if available,
 otherwise would fall back to GLX.

 So things that currently work OK for us (via GLX) would actually suffer if
 macports enabled EGL.

 As I recall, I checked through all this when creating the gtk4 port….
 which has that behaviour.
