We really should look at whether the functionality we are providing is useful to our audience and base our decisions heavily on that. I understand your sentiment, but what it should boil down to is, "Is this feature providing value?" For instance, now that I have backed off on submitting a Ridders' method root finder, I no longer have an explicit use case for MathUtils.sign(), and it could be argued that this method should be removed. As for skewness and kurtosis, my opinion remains that they are little used in the real world (and are thus causing undue debate within the project and wasting time and energy). No one has commented on that remark, as far as I can remember.
