If we wanted to tweak anything else in addition to swappiness that I wouldn't have even bothered to submit the patch since I'll be the first to admit that the precedent set by further growing the Kconfig phase space is not a positive one. That being said, swappiness is one of the more significant knobs in the vm and certainly one of the more likely to be tuned by a distribution.
