The Task Force can certainly consider these broader questions, however, I will note that they are beyond the scope of this particular issue, which is only about roles on the <a> element. It may be easier to deliver a timely Change Proposal by focusing on that specific case instead of the big picture.

As for "strong native semantics" generally, here is the background. There was much past discussion of this around the time ARIA was first integrated. I think everyone agreed that an example such as <input type=text role=checkbox> was nonsensical - it could never possibly be correct to present a text entry field as a checkbox to assistive technologies. It has to be assumed to be an authoring error of some kind. This was something that PFWG and HTML WG agreed on. I think the remaining issues to be worked out are which elements specifically should have "strong native semantics". If you look at the bugzilla bug on this, you will see that there is some disagreement over whether <a> belongs in this bucket. I think it makes sense to consider other elements on a case-by-case basis.
