Extracted from #2124.

I proposed spec text in w3c/webcodecs#412 which put it in WebCodecs. WebGPU group was OK with this direction if the WebCodecs group accepted it.

Feedback on w3c/webcodecs#412 has been negative on including this functionality in WebCodecs when it is clearly a part of WebGPU that interacts with WebCodecs and not the other way around. From that thread:

It's fine not to implement a specification in its entirety, it's fairly common.

Though I agree this is common, I know Apple has taken a hard stance against this as they intend to implement 100% of the WebGPU spec with no omissions. @litherum how do you view the tradeoff between that intent and the problem of "monkey patching" WebGPU from the WebCodecs spec?
