It’s unfortunate they have deprecated it. We how have DXVK which implements D3D11, including compute shaders, for any platform which supports Vulkan. Making that (or a conceptually similar) thing work across platforms is no longer prohibitively expensive.

I believe that approach, i.e. the compute shaders, is the correct thing to do because modern videogames use them a lot, the runtime support is stable and performant now. No need for special HPC-only drivers or runtime components.
