That's a good idea. To get real-world code, once I add Clang support for `SpirvType`, we should be able to generate a good example from https://github.com/microsoft/DirectXShaderCompiler/blob/main/tools/clang/lib/Headers/hlsl/vk/khr/cooperative_matrix.h. I've created a tracking issue for this follow-up task: https://github.com/microsoft/DirectXShaderCompiler/blob/main/tools/clang/lib/Headers/hlsl/vk/khr/cooperative_matrix.h.
