HAD this protection: it's called Design Maneuvering Speed; the speed at which application of FULL available aileron, rudder or elevator will NOT overstress the airplane. It approximates Rough Air Speed.
I believe the investigation into the AA A-300 crash in NYC put lie to that assertion. Design Maneuvering Speed provides only protection in the sense the wing will stall at or before reaching design "G' loading, it is not protection against gross mishandling or undesigned loads, like full and reversed rudder deflection or rolling "g"s.
