I agree that this is a problem.  But if both have alt="", you have the same 
issue, with the additional problem that the UA can't really try to guess based 
on image analysis (unless the UA just starts ignoring alt="" altogether).

The real question is how to maximally motivate authors and authoring tools to 
add alt text whenever they can without forcing them to add incorrect (and alt="" 
on a non-decorative image is incorrect) alt text.

It's a psychology question, not a technical one....  Have we considered finding 
a psychology expert to ask?
