Why is interpretation of WAI-ARIA role taxonomy a relevant consideration for what roles should be allowed for <a>? The rationale for your Change Proposal does not cite "the role taxonomy says so" as an argument, rather it cites the fact that Web developers are already using <a> for some non-link purposes, and it gives specific examples. I don't see any examples there of <a> being used as a slider, scrollbar, progress bar or radio button. So it seems that aspect of the proposal details is not justified by the rationale.

I can see a potential argument for <a role=button> based on the fact that <a> elements are often (mis)used as buttons, and disallowing it may lead authors to make their content less accessible instead of more semantically correct. But that reasoning does not apply to <a role=progressbar>. Since authors are not making that semantic error currently, there doesn't seem to be a practical benefit to allowing it.
