The package is not delivered "as normal" - it's dropped via parachute. The parent poster's point is that delivering things via parachute comes with all kinds of risks in comparison to targeted landings (ex. wind gusts during drop, power lines, blowing onto a roof, parachute failure causing breakage, etc.)

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.
