If the utility requires all the subsystems, then doesn't the dependency exist no matter how the code looks? Of course you can refactor to reduce dependency scope at a code level(the essence of functional programming), but if in order to do X you need to access W, Y, and Z, then I don't see how code changes will affect this deeper truth.
