Why not load the minimal required content for it to look right first (e. g. thumbnail, video controls) and load everything else once the rest of the page has been loaded (e. g. buffer the first few seconds of the video), somewhat similar to hydration?

I suspect that’s what they do already. The trouble is that it’s heavyweight speculative execution that often doesn’t pay off, but it wastes resources anyway.
