a system that can be scaled 333x or pushed into radically different allocation patterns by changing one or two constants seems like an odd choice for arguing that YAGNI and you shouldn't plan for anything beyond 10x/should plan for a system rearchitecture at that scale. That seems very much like a system that thought ahead and picked meaningful knobs to allow drastic changes in use-case to suit the situation.
