+1 They can't ''unlearn'' the stuff they already know. This isn't the experimental 60's and 70s anymore when we just didn't know as much. It's very simple: more mechanical grip, smaller, simple front and rear wings, clean aero from floor/diffuser (even venturi tunnels). Job done. Cars will be massively fast still (if not even faster), especially with the venturi tunnels sucking the car down downforce will be on equal level if not more than now, and cars can then follow each other very closely without very much disturbance.
