Details

We are currently stricter than the WebGPU spec.

wgpu bug: https://github.com/gfx-rs/naga/issues/1945

This requires some work in naga's HLSL backend, other backends should already be able to support it, although for now wgpu checks that all vertex outputs are consumed (with an opt-out feature introduced in https://github.com/gfx-rs/wgpu/pull/4116).
