If you trust the author to use adom="" correctly, why don't you trust the 
author to write the accessible solution correctly? Or equivalently, why do 
you trust that if the use has specified adom="", the fallback is 
accessible? If you are saying that you don't assume this, but that the 
accessible content will always be further tested by inspection with an AT, 
then why can't you use that testing methodology regardless of the presence 
or absence of the adom="" attribute?

You also seem to be assuming that the fallback content and the accessible 
content cannot ever be the same. My apologies if you are not assuming 
this. If you _are_ assuming this, then I must protest. I would posit that 
in many cases (a more-or-less static picture with no semantic 
interactivity), maybe the most common case, they will be the same.
