Ahh yes but of course we do have two ignition systems that have two
batteries that have a diode in between to completely isolate them don't
we?..

See Frank's archived rantings on the subject.

In that case the alternator can short to ground and burst into flames
and the motor won't stop...In theory.

True, but if the alternator falls off and the alternator cable shorts
out and you have no way to cut the alternator out of the system and you
don't have a backup ignition system with an independent power source,
you will suddenly find yourself flying a glider.

But, you're right, a loss of coolant flow is much more likely in this
case.
But a loss of coolant will not immediately cause a complete loss of
engine power. If you recognize the problem, you can pull back the power
to reduce heat buildup and glide to the nearest suitable landing site
and probably still have power available for the landing. With no engine
power at all, your options are much more limited, but even a controlled
crash into the tree tops is likely to be survivable in the Zodiac.
Having the engine fall off is not likely to result in a survivable
situation. It tends to play havoc with the center of gravity.
