It would be really nice to have extreme endgame goals of watering the entire map, eliminating badwater that is unmanaged, storing a couple of years’ worth of water consumption, etc etc.

I will say I don’t even bother dealing with their inter-zone logistics too. I just make one big zone for the whole map and suffer through the long travel times. Makes so much of it infinitely easier to deal with. I don’t have these multi-thousand-beaver saves though like some folks do though, so maybe it changes at that scale.
