And what happens if the kernel crashes or gets rebooted from a watchdog? Or if the bootloader messes things up? The ITS is in an unknown state when we start again. Wouldn't it be better to address this instead? Enforcing an safe initial state seems a better solution that relying on mechanisms that may not be relevant for all cases.
