Marvelous idea...logical too...and flies in the face of operating efficiently. 
But, that notwithstanding, with limited spectrum space available, even after the
expansion of the phone bands, why are we considering reducing the number of 
channels available, by increasing the bandwidth?

Arguments in favor of creating wider than required signals remind me of folks 
who buy a car with a huge engine and then insist they be allowed to drive at no 
less than 90 mph.
