For what it's worth, I think both the change proposal from Laura [1]
and the current spec text, is too complicated and a degradation
compared to HTML4.

The 'alt' attribute is, as far as I can think of, the most successful
bolt-on accessibility attribute in any version of HTML. In part I
think this is due to the simple message we've conveyed to authors:
"All images require an alt attribute". I don't think any of the change
proposals (including the no-change change proposal) has demonstrated
that there is any problem that needs to be solved with that
recommendation from HTML4.

If no one else writes a change proposal to this effect, I hope I'll
have time to.
