The only difference between preload=none and preload=metadata is how much
is fetched if the user doesn't interact at all with the video. Once the
user has begun playing, I think the two mean the same thing: "please don't
waste my bandwidth more than necessary". In other words, I think that for
preload=metadata, browsers should be somewhat conservative even after
playback has begun, not going all the way to the preload=auto behavior.
