Actually, this is one of the most mathematical papers I have ever seen posted here. There is even a theorem and a proof which looks correct to me.

What are your thoughts on the "Extensivity" requirement?

To my mind that seems like a property that guarantees you will end up with a Gaussian, but other than that I do not see why this is necessary requirement of any blur metric. Or did I miss something important?

No, the extensivity property which actually follows from the additivity one is true for B being the second moment as in the theorem, for every blur kernel with a vanishing zeroth and first moment, which is assumed in (1).
