Everyone already knew that f/2 resulted in the same exposure regardless of format and regardless of focal length

"Everyone"? I wish that were true, but there are too many posts on dpreview that prove you wrong, including that Sigma reveiw. "Everyone" did not know that, mostly due to confusion sewn by your singular definition of "Equivalence". That's why I posted what I did, even knowing that it would provide you with "entertainment".

The point of Equivalence, since you still don't seem to know, is that the same exposure on different formats produces different results, ergo, photos from different formats with the same exposure are *not* equivalent.

In your narrow definition of the term. Why is your definition more valid than mine?
