User agents must support the <video> element as part of supporting the 
spec, so it makes no sense to have a requirement that is predicated on 
them _not_ impementing the spec. (It's like having laws that only apply to 
people who are going to break the law -- if they're ignoring one law, 
there's no reason to believe they'll pay any attention to another.)
