The RDA is used to set policy for institutions which do effect people. No matter how stupid an "official" recommendation is, institutions take it seriously because following it deflects blame if something happens.
Boosting the RDA probably filters through to stuff like school lunch programs sooner or later. If school lunches needed to boost protein they'd likely do it at the expense of carbs and fat. Less bread and seed oils, more proteins for the kids - sounds like a win to me.
