The poster is not some 'magic key' which uniquely, or even often, provides that information. For all users the purpose and content of the page needs to be clear, and it usually is, in a myriad ways - the tagging, the other elements, names, site names, etc.  It is not true that if you don't 'get' the poster, you are doomed; it's usually fluff, simply there because the first frame (the default poster) is often black.

Ah, "usually," "often," I notice you don't say "always."

So, it's there. It's an image right there on screen that, by your
argument, is at least sometimes not black and not fluff. That's enough
reason to require the markup mechanism. I have no problem marking the
black and the fluff "presentational," but there's no accepting a global
exemption for alternative text (including long descriptions) for ANY
substantive image on screen.

If it's so vanishingly insignificant--pull it out. Get rid of it
entirely--or support the alternative description mechanisms a11y
requires. But don't tell us we're keeping it, but you can't participate.
