Low priority, but next to FemFX (#179) it'd be nice to have RadeonRays bindings, as we already support the Vulkan Nvidia raytracing extensions. https://github.com/GPUOpen-LibrariesAndSDKs/RadeonRays_SDK
putting into 2.x for now, as FemFX also is. (RadeonRays has a tiny API surface, though spanning 1 standalone, and 3 compatability things (DX, Metal, Vulkan) but I think this should be pretty easy?)
