if its a dedicated flattener than short answer, no. If you use their canon ring, you shouldnt need it.

I just purchased the 80ED SW 0.85x reducer/flattener for my 72ed and canon 600d and the stars look nice and round to me in the corners. If you are being picky then you might need a set of delrin spacer rings to get it spot on but out of the box, mine works fine.

I believe that is correct.....well it is for my 72ed.

The camera looks to still be in the same relative position with the FF/FR now taking the space where the extension was.
