-The answer is: yes, we _do_ have sad, sad humans that really want their WGPU code to work _everywhere_. As Firefox and others use WGPU to implement WebGPU, the above example of Firefox diverging from standard is, unfortunately, today's reality. It _mostly_ behaves the same as a standards-compliant WebGPU, but it still doesn't in many important ways. Of particular note is Naga, its implementation of the WebGPU Shader Language. Shaders are pretty much a black-and-white point of failure in GPU programming; if they don't compile, then you can't use the rest of the API! And yet, it's extremely easy to run into this:
