I flew the MD80 for 20 years. With the landing light deployed you had less clearance than the Max. Side slip was in the manual and we all flew that way. Flew the 737 same way until the 800 was on the property. Boeing said crab MAX, so the company standardized that across the fleet. I was told that the real concern was that a scraped scimitar, or whatever it is called, would ground a plane for weeks and cost big bucks. It is composite and the only repair procedure was Boeing's. Requires a lot more then RR a landing light or drilling out a few rivets. I still think it is ridiculous.
