Okay, it's a fair point that many poster frames may be added automatically and
so the presence of an explicit poster attribute does not directly imply that
it's been chosen by the author. However, that's no reason to not have an
ability to supply alternative text for it. That's a bit like saying that images
shouldn't have an alt attribute because some images may be server generated.
