Outside of demonstrating a complete lack or empathy or understanding of user
needs, is there a technical question here that needs clarification? 

The bug has been clearly defined, the use case has been documented and
explained, and we now need to have spec language that addresses the need. Why
would the editor need to know how that affects one person? There are millions
of non-sighted users in the world today, and each one has different needs,
desires, requirements and circumstances.

If a page author is presenting a visual image of any sort on a page, then there
is a conscious decision to do so, and in selecting that image: there is a
transfer of information happening between the author and the end user. We must
ensure that when that transfer happens, we are capable of ensuring that we do
so to all users, not just sighted users. We need a mechanism to do this - never
mind that it will be abused, misused or ignored by some - it will also be used
properly by many others and will benefit those users who require such.

Is there a legitimate technical reason why this cannot be achieved?
