Thanks Terry_Hebert !
Good question. The reason I have always pushed for us to use the term 'equivalency' are due to two reasons: First; that the Commercial service has differing values for a number of ODVs across the control scope and Second; that customers really need to understand how they might be treated differently as a tenant of the Commercial vs Government services i.e. if we declare an incident for the Commercial service all entities within would be treated to the Commercial (not Government) Incident Response practices and requirements. So I use equivalency (amongst other tactics) as an attempt to incent customers to look deeply at these differences before making such choices. As you and I have discussed over the years; I am fine if a customer makes a choice to accept a risk; as long as that was a well-informed decision and I've done my job contributing to the 'well informed' aspect of that decision 😉
