I agree it would not cost the Ford factory more to use a different hole, right? But chassis tuning is all about compromise.

Cheap Handling Fix addresses "handling" by increasing roll stiffness (same as stiffer sway bars), which keeps the RV from swaying side to side as much which is what everyone wants, but at same time likely causes other deficiencies in ride quality. Ford engineers and motorhome owners appear to disagree where that compromise should be. Or perhaps Ford engineers didn't anticipate that so many chassis would be used in applications where the center of gravity is so high. A typical truck can easily have a lower Cg than some newer motorhomes.

Stiffer sway bars unfortunately reduce suspension articulation, and generally lack of articulation and or suspension travel is considered detrimental to a comfortable ride. It's similar to stiffer springs. They too reduce sway side to side, but can reduce ride comfort at same time. Obviously it depends on magnitude of changes and personal preferences, and types of roads driven.

Most of this stuff is studied in mechanical engineering, and I'm sure Ford chassis engineers get a lot of additional specific training.
