Re: [whatwg/streams] Add URL.createObjectURL(stream) support (#480)

Right, so obviously for this case the spec would have to declare that, unlike `blob:` URIs created from Blobs and MediaStreams, URIs created from a `Response` object can only be fetched once, and when attempting to fetch it, it first checks if the stream is disturbed and gives a network error / the URI is automatically revoked.

That would actually be less leak prone, so benefits all around.

That might help the MediaStream use case, but it doesn't help e.g. downloading files that are generated/processed client-side that are too large to hold all in memory at once.
