This still gets back to the question: Do we expect browsers do
anything other than minimal amount of network traffic for markup like:

<video src="video.ogg">

And if expect them to just do minimal amount of downloading for that,
why do we need another state meaning "I know you'd just download the
minimum if I didn't say anything, but I still want to tell you to just
download the minimum"?
