[Question] D3D11 buffer Vulkan interop, similar to IDXGIVkInteropSurface

I'm working with an external Vulkan renderer that needs access to the VkBuffer behind a D3D11 buffer.

Would it be acceptable to have an IDXGIVkInteropBuffer interface, similar to the already existing IDXGIVkInteropSurface, it would require exposing the D3D11DeviceExt::LockBuffer on D3D11Device.

If yes, should I PR LockBuffer on D3D11Device first, and then the interface?
