Apparently you aren't using OpenGL then,

My desktop apps that use hardware acceleration and I still care about are DirectX.
In any way keep reading news and adjust your stack and rewrite your applications every time MS sneezes. Good luck. I am pretty happy so far investing in features rather then rewriting.
Unlike Apple, Microsoft is dead serious on maintaining compatibility with minimal hassle.
Or OpenGL/Vulkan in Win32 or UWP sandboxes for that matter.
The only way to run Win32 on Windows 10X and possibly in future Windows 10 versions as well, even if it takes a couple of years more, just like it is happening with Apple and Google's platforms.
More seriously. Windows does not prevent me from using Win32 so no need to use ReactOS and I did not ever have a single customer complaint about not using UWP/.NET/WinRT/Whatever tech. So in my areas of business where it concerns desktop apps that "warm feeling" means zilch fro a practical standpoint.
