If memory serves me correctly someone did a test that showed regen effects by using the tekno electri clutch with mech brakes and then swapping in a regular pinion and using motor brakes. They had longer runtime with the pinion and motor brakes, indicating regen braking was recharging the battery somewhat.

My understanding of motor braking was that the esc placed a load on the motor during braking, as opposed to the vehicle placing the load on the motor during acceleration. Maybe to simplified, but with DC current it has to flow one way or the other. I do not see a method to "ground" it out, as it is a closed system. No wire leading to the dirt. Unless you attempt to disapate the braking force into heat, like a mech brake does.
