Hackers would probably also love to consider that a lot of hardware that has code that depends on lat/lon for internal calculations can have all sorts of weird problems. When you are exactly at the pole longitude can switch from +180 to -180 rapidly and that can be a catastrophic edge case for anything that needs to do positioning. I had the pleasure of watching an expensive drone crash into hull of a ship and sink into the ocean at the north pole for this exact reason.
