Rick, all that does is drive up the price. The FBA architecture simply has not kept up with ECKD and there'd be a whole boat-load of work to be done to bring it up to snuff. Heck, even RESERVE/RELEASE is not architected for FBA. And there's a lot of the advanced disk functions that require CKD specifications. All of that would have be enhanced as well. The fact that z/OS isn't into FBA must also be considered, affecting the marketability. I just don't see where the business value is to be found. I do understand the elegance of what you propose, but that's not good enough any more. There was a time, though.... Could it be faster? Sure. How much faster? Is it fast *enough* as-is?
