Sadly the facts disprove the theory and you are perhaps exposing yourself to risk in the belief.
From memory the Armidale audit cited 4 ATSB incidents - three certainly IFR/IFR. Williamtown certainly cited IFR/IFR (RPT) head to head.
More recent audits identify which a/c as a risk - the one off the CTAF frequency talking to CEN.
It's your belief - good luck with it
