Yes, completely. In addition, sighted users relying on alt text for
missing images will likely not see all of that text, as it's (by
default, depending on CSS) clipped to the image size and not wrapped.

Well, i agree with you. Steve did a lot of work on them but at that
time there was no longdesc allowed to be mentioned and no
figure/details stuff.

I had to stop working on the replacement, partly because of the
politics at the time but mostly because the recommended solutions were
in flux. If they've settled down, i'd suggest:

1. the HTML spec should have no more than roughly three paragraphs
about alt. Very few people will read more, and those people will
probably be willing to read a separate document.

2. The HTML spec should point to a non-normative document under WAI's
control that gives examples in more detail.
