I haven't read enough books or tutorials lately to know how much
@longdesc is mentioned.

However I'll note that clearly these books and tutorials haven't done
a very good evangelizing @longdesc, given how little it's apparently

I continue to think that "it has been implemented" only proves that
"it can be implemented", not that "it's a good idea to add to the web
platform". As a browser developer I'm always happy when i can simplify
my product, I would expect the same to be true for your engineering
and QA teams.

Given how little @longdesc is used, I would be very hesitant to try to
explain any aspect of AIRA using "it's like longdesc", for feat that
it wouldn't be used more than @longdesc has.

Can you provide an example where @aria-describedby does not work as
well as @longdesc in the real world?
