AD kicked this off on 4 Oct, and clarified a point or two on 5 Oct.

No response to any posts on the points in the OP since, and since I'm selfish, specifically no response to my request (on 5 Oct).

AD added a new item on 7 Oct, but hasn't posted since; specifically, no response to my request (on 7 Oct).

What is it reasonable to infer from this?
