Dan, you're right.
Gwave considered attaching the rope to the bottom anchor the same way as for abseil/rappel, but for going up and not down. So when you finish the pitch, you retrieve it the same way as after a rappel, but from the top and not from the bottom, and in theory you wouldn't have to get down to release it from the bottom anchor. Then different scenarios were considered in the discussion what would happen if we did that.
