That depends on who you ask. OpenGL is in the deprecated API section on MSDN[1]. Because of the ICD model, Microsoft can't prevent GPU vendors from adding OpenG

That depends on who you ask. OpenGL is in the deprecated API section on MSDN[1]. Because of the ICD model, Microsoft can't prevent GPU vendors from adding OpenGL features, but they don't bother integrating it with modern Windows APIs. You can't create an OpenGL context on a DirectComposition surface or in a UWP app. It integrates poorly with the compositor. You can't get composition feedback, and most drivers will flicker or show artifacts when windows are resized. OpenGL apps don't get windowed-fullscreen optimizations and you can't control when they enter exclusive fullscreen mode. I don't think you can use windowed-stereoscopic or windowed-HDR either. All these issues push developers away from OpenGL and towards DirectX, which is what Microsoft wants.
