I’ll put in my 2 cents. In general, all other things equal, I think:

Exaggerate a bit to make my point...a 100% decel lock means both tires are forced to rotate the same speed during deceleration/off throttle, it will make the rear act like little more like a pivot, and less willing to rotate (therefore front being pulled into corner like Rusty said). It will be more pronounce in slow speed, tight corners. So I would think it’s not desirable for autocross.

Now if you have a rear end that’s all over the place, bumpy surface in a high speed braking zone, a high decel lock may help calm the rear end down during braking, making the rear end more predictable.

But of course, like others said, a lot also depends on driving style, and perhaps power level. A driver that prefers to use sharp steering input and heavy jab braking may partner better with a high decel lock versus smooth driver with gradual steering input and linear braking style.

Then again, handling is a package deal...at any one moment rebound, compression, camber and toe curves, LSD, all work together.
