What happens if there is a segfault and the watchdog is off? This is not a regular PC and I don't see a hardware reset nor a control-alt-delete would resolve things.
I imagine you can disable R&D mode once you have successfully booted and the reboot count has been reset to zero.

If you were to disable the lifeguard reset the worst thing that can happen is the device hangs instead of rebooting - if it hangs you just pull the battery out for a second and reinsert. If it is indeed necessary to disable the lifeguard reset to resolve the reboot issue, the inconvenience of having to pull the battery surely outweighs the inconvenience you would experience from a reboot loop.

Pulling the battery is the ultimate three-fingered-salute, essentially the same as power cycling a PC which I've had to do from time to time in Windows when it locks solid and no longer responds to the keyboard/mouse.

Fair enough.
