Gaming is all about legacy software, especially single player games. As a gamer I'm very happy that almost all older games still work on Windows today (either directly or using an emulator like DOSBox). (Of course that does not mean that the OS needs built in OpenGL support. If you can convince an old game to use some kind of OpenGL-Metal compatibility wrapper without needing access to the game's source code or support from the original developer, that's fine with me as well.)
