I suspect that part of the problem is that some people use "Assistive
Technology" and Screen Readers interchangeably, which is a problem.  There are
many Assistive Technologies that are used by sighted or partially sighted users
that may also avail themselves to ARIA properties (the latest version of
ZoomText comes to mind, which is both a screen magnifier and a screen reader). 

If this techniques is intended for screen readers only, then it should clearly
state so, and avoid adding confusion by referencing Assistive Technology.

But is that not a given when you speak of "Full Semantics"? If you are instead
envisioning some partial, specific semantics, then say so as well.  If
@aria-describedby is pointing to an @hidden ordered list of links (completely
legitimate and possible with this current change), then of course a tool such
as ZoomText needs to navigate into that part of the ax tree, and further it
needs to be rendered visually on screen.

I look forward to seeing how this might look (outside of the fact that the
entire Issue 204 decision currently has 2 Formal Objections filed against it).
