There is at least one commercial EV aircraft that can do it, but frankly it won't be as big a deal as it is with cars. Cars are speeding up and slowing down all the time. Aircraft generally speed up, stay fast, and then slow down at the very end of the flight. And for most aircraft, the entire flight is powered from takeoff to landing. It could be useful in emergency situations where the pilot is at risk of overshooting the runway.

For aerobatic aircraft it could be a big deal. High power motors and the desire to be as light as possible will probably drive power recovery and even crazier stunts at airshows.
