I think the only reason these Comfort Plus "Basic" fares exist is so that Delta can roll out First Class "Basic" fares. There's no other reason, IMO. A company of Delta's size is not moving the needle in any appreciable way with tiny incremental Comfort Plus sales on the margins for middle seats.
This sets the stage for First Class seat selection in First "Classic."
