I'm not sure that I can agree with this. If all the threads were the
same thickness (between DIN and yoke) then it would be true...
Are you sure there is more contact area for the DIN? Are you sure that
the threads are the same strength? Is a hollowed tube stronger than a
machined, solid metal, screw?
The captured O-Ring thing also bothers me since (I think it was) Bill
Gavin or George talked about this. When connected to a tank valve, are
you saying that the O-Ring in a yoke is NOT captured? What keeps it from
expanding and breaking, then? Neoprene does NOT deal well with 3000PSI
(or higher) against it unless it's backed by something a bit stronger.

It is hard to disagree with a pro-survival decision,
It is even harder to engage in prolonged arguments
with someone who consistently makes anti-survival decisions.
