I think the problem and source of most of the confusion comes in is what people are actually comparing...

Across format sizes, are they maintaining magnification (FOV) or are they maintaining perspective (distance to subject)

You've made good proofs for your side of the argument when maintaining magnification and their is good reason to compare systems that way. However if for whatever reason the person wants to know the comparison for what you get when you stay in one spot then you've not maintained FOV or magnification and therefore the DOF changes.

2 schools of comparison, both right, it all depends on what you're really comparing.
