Here's my theory...
Makes sense to me that they're more common in FWD because the tranny mounts directly to the engine and the axles. So, driveline torque affects the engine differently than a RWD car where the diff is separately mounted to the rear subframe.
So in a RWD platform, if the engine rotates say 5°, it has much smaller effect on the rear wheels due to the final drive reduction in the diff being separated from the engine/tranny assembly, so it may have a 1° effect on the wheels at most.
On the other hand, a FWD platform if the engine were to rotate 5°, the wheels will also rotate 5° because the entire drivetrain (and final drive) is bolted together as a single assembly.
5° is extreme, but just an examlple.
