Back around the end of February Khronos announced a "3D Portability" initiative [1], which would abstract over Vulkan/DX12/Metal. As I understood it, this could be a pure library solution which wouldn't require support from the platform and so would be less vulnerable to blockage by the usual walled-garden merchants. It was also mooted as a possible basis for WebGL-TNG. Unfortunately I've seen nothing but tumbleweed ever since, which makes me suspect that this is one of those Khronos initiatives that never makes it out of the hangar, much less off the ground.
