Re: [whatwg/fetch] Warning: header & stale-while-revalidate (#913)

I'm not sure and it might be a more general problem, as browsers don't support https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Accept-Charset either. `Accept-Charset` is only supported in the sense of not being able to set it from `fetch()` and the browser not doing anything funny if it appears in a response. So again, it really comes down to the criteria of what makes a supported HTTP header. I suppose I'd say "no" for both and only use "yes" if there's some processing model in place that is also supported as is the case for `Cache-Control` for instance (with caveats, as documented on that page).
