The idiocy of locking the spare is not new. I have a 2008 F250 and the special key was nowhere to be found and the dealership was useless. One dealer wanted to remove the entire bed to get at the lift winch from above. Spent a couple hours getting the spare down and then wound up removing the lock portion of the lift winch.
Actually might not be bad having to lower the spare to get at the tailgate wiring. Things tend to get caked with mud/dirt and corrosion, so when you do go to lower the spare, it may be frozen or the tire doesn't have any air. Lowering it a couple times per year will ensure it works if you do have a flat. Assuming things are working fine, most of the time and effort is getting the handle out from behind the seat.
