Until, I see some lab tests to replicate, I'm doubtful. Ski helmets are very similar to bicycle helmets, and I see bicycle helmets shatter all the time.
and sometimes they should, they are design that way, as the helmet break it take the impact away with it.
kind of like car front end crush zone, they are suppose to crush in to absorb the impact, because when the do not the occupant with absorb it and cause internal injuries

^ read why the other shelf can sometime break- not a good thing in a motorcycle as there is usually multiple impacts, but in a bicycle multiple impact is unlikely. but you are right, there is not enough testing on this.
