Many responses are related to RWD cars but OP (& I) are trying to figure out if this is even more important to spec on an AWD car.
I expect to mostly drive my G80 M xDrive in 4WD or 4WD Sport (or whatever they call the rear-bias AWD mode). I may do an occasional track day but I'm not into autocross or drifts & donuts. I may switch to RWD when I want to let the tail loose and have some safe fun on a twisty road or if I'm doing a u-turn at that one traffic light close to our home in the middle of the night
I can see how having variable traction control support in RWD mode can be beneficial, but I'm not sure I "need" it or even use it enough to actually learn the different settings
