I agree with that NOPERF.
Generally, the annoying patches of ice are no greater that 10 square feet on the wing root of the 737 NGs. There should be some reasonable limit for upper wing condensation frost caused by super cooled fuel. These ice patches generally manifest themselves several feet behind the leading edge, and I would be very surprised if engineering studies showed they represent a significant hazard.
I hope Boeing can modify the "Clean Wing Concept" with the FAA to introduce some common sense. The "Clean Wing Concept" was an overreaction to the Air Florida crash.
