Those are almost as benign as the low speed regime.

If I were setting policy, the captain would take control at taxi speed unless intervention was required for proper directional control and braking. The PM Captain is in a better position to note the abort speed, verify spoilers and verify auto brakes because they are already cross checking the instruments while the PF FO is primarily looking outside during the takeoff and already maintaining directional control. Transfer of control at high speed during an abort is just adding risk.
