Yes, exactly that is what I mean with the original question.
I still remember German language DIR descriptions explaining why helmets are an absolute NO-GO in technical diving.
I also know commercial divers who dislike helmets generally and hate it when they see them in at lakes.
There was however, never a page or post saying the same about using a helmet for open water dives - it was simply inconceivable.
The helmet can have severe disadvantages.
Disadvantages typical 'forums posters' worldwide would routinely call 'suicide' and a reason have the poster removed from the human race and send to a waterless planet with warning sings in orbit forbidding beginning divers to ever go there.
Catching on the hoses in OOA situations for example.
Generally there is a very realistic danger of the helmet getting stuck somewhere and dislocating mask and hood.
Got stuck myself with my now mothballed second generation helmet and had to remove the hood in very cold water not to get choked.
With the helmet tank light there is the additional complication of the light cable crossing both hoses in front of the left shoulder.
I remember fairly recent discussions addressing one of those topics critically concerning normal open water dives and even cave or trimix dives.
Regarding sidemount I was told it to be 'impossible taskload' to identify the longhose if I am not breathing it constantly (b*llsh*t, but still a common discussion topic).
I am telling people that two long-hoses around the neck cross each other and have no advantage to the long-hose/short-hose configuration because of that.
Now I have a two handed OOA routine...
On the other hand: not including a goodman mounted 2000lumen light in in the OOA routine somehow will probably blind the OOA diver as securely as not thinking about the helmet light.
