How are you suggesting to write shaders in the browser if they are expected to be in a binary form?
WebGPU community group is open to anyone interested: https://www.w3.org/community/gpu/
We can compile and run c++ code in a browser with WASM versions of clang, why would it be any issue to compile glsl / any other language to spir-v ? That's already what almost everyone is doing with spirv-cross / shaderconductor on the desktop
It seems you speak with "we", as if you were part of the committee? If that is a yes: how can we become part of that committee to amend this mistake? Who has voting rights?
