But isn't this what the Issue 204 decision wants to do? To "un-hide" the
semantic structure under certain conditions (when referenced by an ARIA
attribute) so that the structure and content remains intact and "rendered" by a
speech synthesizer?

Right now, {display:none;} and {display: none !important;} are respected by
screen readers (as it maps as such to the AAPI). This also brings back the
question of what/how ARIA aware screen magnifiers are supposed to process this
