This is a good valid point. If we expand on this to incorporate a roll-over switch to disconnect the entire electrical system rather than an individual componant would be more comprehensive. This is easily done with a continuous-duty solenoid and a factory rollover switch.
For additional security you could lock the solenoid out with a remote transmitter/key fob thing.
But then you get back into the buggaboo of wireing complexities.
