The "reduce" operation, of making an $$n-1$$-dimensional system from an $$n$$-dimensional one, is coded in slightly different ways in various operations to construct (mostly stochastic) dynamical systems from box models. It would be nice to combine those into a single thing, and also to have the systems themselves be able to reduce their dynamics when there's a conserved quantity.
