Indeed, and the one change to keyboard design that would provide substantial ergonomic opportunities hasn't been seriously approached. The key switches are too large to provide layouts that fit hands that are narrower or shorter than somewhere larger than average. Lillian Malt kicked things off in the 1970's with the Maltron, a (brilliant) workaround for key spacing being too large for her hands. We've been beating around the same oversized components ever since, trying to squeeze out a drip or two of better ergonomics. Further useful pursuit of improved keyboard ergonomics requires keyswitches with a size and travel distance that isn't informed by the recent memory of typewriters and manufacturing limitations of the era of Cherry's original design, and produced in volume to at least Cherry MX standards. It's time to move away from typewriter-defined hardware.
