You need to be careful here, because we have a real tendency to get stuck in local maxima with technology. For instance, the QWERTY keyboard layout exists to prevent typewriter keys from jamming, but we're stuck with it because it's the "standardized solution" and you can't really buy a non-QWERTY keyboard without getting into the enthusiast market.
I do agree changing things for the sake of change isn't a good thing, but we should also be afraid of being stuck in a rut
