Switching to a lower final drive will lower torque driven to the wheels. So it doesn't so much aid traction, but it reduces your need for traction. However, unlike comparable band-aids such as traction control, at least the final drive gear change offers the advantage of taller gearing in exchange.
I have not seen any production cars use dynamic control arms yet, but I wouldnt be surprised if there are high power RWD OEM cars like AMG or something using it, or working on it. The advantages to dynamic alignment are endless, so I doubt it will take 20 years... I would say any day now.
