That falls into the question of "Are you above the very definition of what a dimension is, or are you just a non-physical being that happens to have greater AP than character who happen to be physical?". So, basically the difference between Type 2 BDE (The thing that the Tiering System currently says is Low 1-C at minimum) and Type 1 BDE + AP. I wouldn't consider your example to be a valid case of 1-A, but a realm that's depicted as the much "larger" container of a dimensioned reality and then described as above spatial dimensions entirely, would certainly be one.
So, all-in-all: I understand you have doubts, but these doubts are not really faults pertaining to the proposals, since they're answered by simply referring to how we define these concepts already. Scaling, not definitions, is what i aim to change.
