The problem is that there are _three_ states, not two:

 1. Image is not important. (alt="")
 2. Image is important, alternative text is available. (alt="...")
 3. Image is important, alternative text is not available.

Case 3 is the one we are discussing. Cases 1 and 2 are well understood and 
nobody is suggesting changing them.
