Is that something a custom wiring hardness could solve?

Holy crap. How is there any legitimate justification for designing it that way?

Without such an internal battery, automotive thieves could instantly mask the car's location by merely pulling the fuse or disconnecting the main battery. I imagine that is their justification (not that I agree with it).
