if you read back in the thread you will see it was in response to
chaals asking me for a reference to my previous statement:

"I also think that some AT will simply not implement the rich hidden
content model as described, The NVDA developers have not implemented
longdesc due to it having no visible UI (for example)."

in other words it doesn't help to have stuff exposed by browsers if AT
don't make use of it.
