These are similar risks to the Google Wing concept. The parachute has fewer risks of collision with the vehicle since the vehicle is nearby for a much shorter period of time and is not making a flightmode transition. The issue is simply a matter of minimum required landing area. Hovering could be a little smaller than parachute delivery (16 ft), but still must have a "safe area" is approximately similar because the vehicle must hover without nearby obstructions.
