OpenGL will never die, it will be virtualized with Zink
From my understanding, the main goal here was for Chrome to handle WebGL on Windows using Direct3D because OpenGL driver support on Windows is not good. But it's aiming to be a universal graphics shim for many platforms.
Chrome, Firefox, Qt, and Krita all use it.
Virtualized was always it's end game and where well used APIs go to die.
At this point, OpenGL is more important in being fully compatible than in being fully performant. And none of the graphics card guys care about that.
