By not providing an alt attribute for the poster we are not discouraging its
use for any purpose, we are only making it more difficult for authors to
provide accessible alternatives for the way in which they use poster.

I don't see why we would ask if we need to make the poster accessible "as well"
as the video.  As far as I see it the poster and video are two distinct pieces
of content, in the same way that the cover of a DVD case is not the video
within, the poster is not the video.  Is it true that often, perhaps in most
cases, that the poster will be a frame, likely the first frame, of the video,
yes.  Does this mean that it is not important for authors to be able to provide
an alternate textual equivalency for the poster, no.
