No 3 Active controls.
Ailerons respond to gust load imposed on the wing. The L1011-500 had them. The outboard ailerons (normally locked out with the flaps up) respond simultaneously and symetrically to absorb the increased wing root bending moment, limit the load on the wing and negate the need to beef up the wing structure.
No 5 Direct lift control.
Another L1011 thing. Used on the approach the spoilers are deployed to a null position and modulate around that point, improves pitch axis control and handling.

Not only engine reliability but systems reliability and redundancy also, including, for instance, the ability of the APU to be started in flight after a cold soak.
Engine health monitoring is also a requirement.
