Rationale is provided for unbacked region descriptions; see the paragraph beginning "DOM elements are expensive…". Oh, now I see that you also asked for "details of how [unbacked region descriptions] may be implemented to hook up with accessibility APIs." Describing such details is out of scope for the HTML spec, so I don't see why people would have to provide such detail in a Change Proposal. I note that the only other Change Proposal on the table for ISSUE-201 also doesn't provide such detail. Ted
