The wiring between rotors is effectively a static rotor. In the stacked 
rotor version it is all 1:1.

In a flat version, if I understand you, if it is permanently fixed to 
something other than 1:1 it doesn't do much cryptographically 
(Kerckhoff); if it changes per key - well, a rotor changes even more, 
sometimes per letter.

I guess they thought 3/4 rotors was enough.
