Electrical components must protect themselves, as their circuit designers are the only ones who know what the design limitations are.

That's an excellent point but then how come we don't stick with the same logic that was used to design the spikes and see fuses on all electrical components? Albeit the jags have an over temperature shutdown but what of the Talons and Victors? The Victor manual specifically states:

Ensure there is a circuit breaker either inline with
the 12V power input to the speed controller, or inline
with the motor. Use an appropriate circuit breaker for
your application to ensure that long term exposure to
a stalled motor (high currents) will not overheat the
Victor.
