LOL and it probably would be "better" from a performance standpoint. But at what cost? We like climb perf. Airlines only care about it to the extremely limited extent that the lack of it actually prohibits you from doing a market. That's rare and that's the extent of it. If a GTF 757 made the amount of sense plane loving pilots wish it would they'd build it.
