It’s fine for practically all existing applications. There’s no real reason why Apple should deprecate it instead of opening the source and letting pro apps that rely on OpenGL continue to use this wrapper. The community could implement newer API features, and then everyone just links and includes the version of OpenGL on Metal that they want. Wrappers are used by the majority of apps anyway, for example WebGL. Apple doesn’t get to say: “We want your JavaScript apps to use our API instead, and we’ll make the development experience subpar if you’re using WebGL.” — they shouldn’t have that kind of power over C apps either.
