Alpha. Your post is not factually correct.
You state “ every time there is a new risk mitigator it will be implemented “
We have a number of different safety standards set on affordability. For example some commercial aircraft are approved by CASA to operate with just one pilot.
They clearly do not in this case( one of many) mandate the risk mitigator of another pilot.
And it’s not the minimal risk we are PREPARED to accept. It’s the minimal risk we are FORCED to accept.
