It's likely there will be a need for a C++-level meta-API that can work on top of Vulkan, D3D and Metal. There's already been discussion of making such a thing. It would be nice if that could be exposed to WebAssembly via Emscripten.

But to what degree might this 'meta-API' be different than WebGPU/JS? Might this effort effectively end up creating two, new APIs, each with different vocabularies (one for JS, another for C or C++)?

I mean, that's going to happen anyway.

The whole point of Vulkan/Metal/DX12 is that since GPUs have their own MMUs it's totally OK to seg fault your own process from the GPU side. You just crash your process, but you don't take down the system.

That line of thinking doesn't really translate well to a JS API.
