Makes sense. I'm hoping it's coming soon. It feels like most of the functionality is already there with piping and water pumps. Maybe a mechanical water pump could be moved to basic engineering rather than mechanics considering mechanically driven water pumps using windmills/waterwheels are a relatively old technology.
I'd actually not expect it this year, unfortunately, at least the internal roadmap is focused on different stuff for this year. (Including boats, food system overhaul, maintenance, multiple government and a load of other stuff I can't announce yet) I'd see it more towards a major update with animal husbandry, which wouldn't be this year. But stuff can always change.
