@JAWS-test as I know you have been following along with this topic, as in ARIA ticket #1381, I should also hope you remember that it is not for this spec to determine what what the correct output would be for screen readers.

Rather, until a feature such as inert is available, there is no good way for authors to completely hide content outside of modal dialogs and other such components, and the reality is techniques like this, using aria-hidden and negative tabindex, is necessary to both hide the content from AT while ALSO making sure it cannot receive keyboard focus.

This issue, much like the work in ARIA, is an effort to at least mitigate instances of authors doing things like <body aria-hiddden=true> and <button aria-hidden=true> where the latter is widely agreed to be problematic because any dialog that appears on the screen will also be a child of body, and the former can still receive keyboard focus, even though it's hidden to AT.

So, again, while I appreciate the ramifications that your question alludes to, this issue is to help STOP the misuse of aria-hidden as setting up these rules will at least allow conformance checkers like the HTML validator to produce warnings. Both of my examples currently flag no warnings or errors in the validator. The completion of this issue will help change that.

disallow aria-hidden on the body element #221
