I've hoped for something like, say (just wide thoughts) emergency parachutes, or going into autorotation in case of power/comm/control failure...

  Some -- including the one used in the video -- can be programmed to automatically return home (based on GPS) in case of a comm failure.

    Comm failure is a good risk to guard against but that won't help with a damaged craft.
