Get Over It !!
3D flight in an of itself is not dangerous. Hovering over the runway is not dangerous. The problem I have with the fad these days is those people walking out and touching or grabbing the hovering aircraft.
I fly big airplanes, I fly jets, I fly helicopters, etc. The MAIN thing we all need to do is communicate. The guy that yells at someone for hovering over the runway while he's doing it, is more dangerous than the guy doing the flying.
Act like adults, and TALK with people at a proper time, and you'll be amazed at what can be accomplished.
