Robert,  

Someone would need to check with Craig Partridge, but I believe
that "only" (or "ONLY") in the above is not strictly correct.
It may have been the primary reason, but, no matter how often
"only" is repeated a desire to permit minimal configurations
did, I am quite sure, figure in to the equation.
