It is. I can only begin to imagine how complex such programming could get.

Let's look at a (fairly) straightforward scenario: Getting most of a wing blown off, like this Israeli F-15 did when it crashed into an A-4 Skyhawk. Obviously, if you pull up, the lift you're asking for is no longer going to be balanced, and will cause the aircraft to roll into the missing wing. Thus, there is going to be a strong pitch-roll coupling, most likely stronger than your ailerons can compensate for. The best way to compensate for this would be to limit pitch to the max that you can counteract with aileron, and mix in substantial amounts of aileron (and differential vectoring) to counteract the undesired rolling moments. Additionally, by yawing the aircraft, you could produce a significant amount of (lateral) lift without excessive undesired rolling moment - think of it as flying knife-edge, so that the fuselage produces all the lift and the wing produces none. From there, its up to the pilot to maintain the necessary airspeed he needs to preserve this control authority, steady the aircraft, and decide what his next move is.
