I heard that it is good or recommended to use them with Carbon cranks. I found also that LOOK pedals have quite long threads, so you can change Q factor without risk.
My bad, I was getting at the fact they might be there just to protect the anodizing or glossy paint i.e. avoid biting into the crank at that spot, but then - which is why I pictured the spindle - that interface was already as smooth and round as a washer.
I still can't get my head around the Campy's notice mentioned above though ...
