Most of these settings are done for feel and the best lap times, usually a combination of both.
The only reason I would adjust for chassis roll, is if the car seems to take too long to recover in switch backs(too much), or if it is traction rolling(too little).
Don't forget, chassis roll (or pitch) front to back is just as important, but that isn't set as much with camber links as it is with anti squat, kick up, ride height and shock tuning.
All for the same reasons as chassis roll.
