Plausible and not implementable. A conformance checker will never know
what precisely is author's intent. And I don't expect non-visual user
agents to implement such image analysis heuristics just because spec
authors think they'll do it. From an implementation's POV, that's plain
crazy, will double or triple the size of implementations and will
probably never be good enough to serve the user efficiently.

I have no time for rhetorics. Just the fact the alt section is what it
is today - and why it is what it is today - scares me to death about the
whole html5 doc. Reminds me of the other "kill the style attribute"
crazyness.
