Currently, aria-hidden=true is a boolean attribute value. Thus 
aria-hidden=false is only informative. I saw that James proposed that 
aria-hidden=false should have an effect. And I suppose @discoverable 
would be no different from aria-hidden=false if James' much sensible 
idea goes through.

It is not important to myself that there is no ARIA interdependence. 
But I thought the purpose of the solution that was put in the spec, was 
to solve the hidden-but-discoverable issue purely from within HTML5, 
without ARIA. This in order to not thread on the toes of ARIA. Because, 
logically, if aria-hidden=false would be necessary in the @usemap/@name 
case, then it would make sense to have the same rule for, for example, 
the @headers/@id case too. And thus, as result, there would be no 
ARIA-free solution in the spec.

From another angle, however, it might not be very important to save the 
independence from ARIA as I believe that we thread on no-ones toes if 
A11Y APIs *do* unhide everything with aria-hidden=false.
