In depth

A function is how an option only one backend has is asked of that backend alone. Traced indirect light and reconstruction are WebGPU's, and WebGL2 refuses either in words when handed one: right for a consumer who asked for it there, and noise for one who wanted it wherever it runs, since every device that fell back printed a refusal. Called once for the backend that draws, and once more for WebGPU's timing request where WebGPU is tried. What would make it wrong is a consumer needing to know why the backend fell back before choosing, which reason on the result says after the fact and nothing says before.
