This AMU madness is running amuck! Next, the mythical Aussies will be demanding the inclusion of Tim Tams and the Japanese will add Pocky chocolate sticks.
How about agreeing on the following requirements for AMUs:
Ingredients: must contain chocolate, gluten, lactose, sugar, and fat -- no vegan cardboard wafers allowed!
Geometry: must be stackable to the height of the DFA 150-450 -- as tasty as chocolate rums balls may be, they make a poor basis for metrology.
Dimensions: must be K-mount compatible -- the diameter should be should be similar to K-mount so that the cookie stack presents a pleasing and tempting counterpoint to the lens without being larger than the lens.
All in favor, say YUM!
