There's no black magic about flying helicopters in cloud without stability systems or autopilots as long as you've got the requisite instruments. Even on limited panel (ie no attitude indicator), it's doable, but the key is training.
One prevailing view in Australia is that teaching helicopter pilots a little bit about flying on instruments encourages them to take risks that get them into trouble because they push weather limits. There's no requirement for instrument training in our CPL syllabus, whereas fixed wing have to do a few hours, which I think is a cop-out to cut down training hours and therefore cut down the considerable expense of getting a licence.
I don't agree with the "don't expose them to it" argument at all, and would suggest that a bit of instrument training combined with sensible advice about pushing personal limits would save lives in the long run.
