Question/feature request: NVidia VRWorks extensions

[XenoPL]

Hello, I haven't seen noted as implemented, hence the question. Would it be possible to implement NVAPI DX11 Variable Rate Shading via translation to generic Vulkan extensions? https://developer.nvidia.com/vrworks/graphics/variablerateshading

It could help DX11 VR apps, that can do foveated rendering.
