kMaxBindingsPerGroup is not a real WebGPU limit. Code in Dawn that uses it now uses dynamically sized vectors, optimistic stack_vecs or a different limit like kMaxDynamicBuffersPerPipelineLayout. The CL introduces kMaxOptimalBindingsPerGroup=32 which is used to size the static portion of stack_vecs, but the value is tentative.
