That's because it's all a big experiment with design/engineer teams that don't seem to include anyone with a sport science background that understands biomechanics and how it applies to mountain biking - a discipline extremely different from road biking. Bikes for the consumer need to be designed primarily around how the human body works first, then the environment they are are working in and finally how the bike best performs in the real world. A height of 5'8" up to about 6'2" seems to be the prime territory where bikes designed for performance mesh really well with body size for aggressive riding. Start getting much past either of those heights and compromises are going to need to be made, either on the bike design or on rider comfort.
