jarhart: because if you will hold the position, it can be in absolutely any position - you can't expect what it will be and what consequences it will cause.
If there is single configured position, you will always know. Adding more points of certainty can always minimize possible damages.
Adding more points of certainly only makes the outcome more certain, not necessarily less dangerous. Yes, with zero pitch you always know what the pitch will be in a failsafe situation, and you know it will be a DANGEROUS one because it will maintain the energy in the rotor. The spinning rotor blade is what sends people to the emergency room (or worse.) This should be our ONLY concern!
With hold position, it's not random, it's whatever you were doing, so the helicopter will keep doing what it's already doing but only for a few seconds because without power the rotor will stop spinning quickly, then the helicopter will just fall. This isn't a thought experiment. Smarter people than me have concluded after years of testing that throttle cut and position hold is the safest failsafe, which is why it's so often the default.

Next reason is, that if you will set non zero pitch that is too high, it will very likely also cause boom strike at the impact which mean next major damages even if the rotor is not spinning at all - this is possible to prevent.
If I've lost control of something that can kill somebody, my only concern is preventing injury.
