We could benefit from water mill powered cableway, which will requires rope. The core's terrain is basically well suited for it. It would also make traversing to the other hill a piece of cake if someone is crazy enough to do it.
That is sensible for 21. century high value cash crops. Less so for BC food crops. At least if they are supposed to be affordable.
Although speaking of ropes, combining Plant Textiles (Hemp) with Build Docks/Warships may advance the development of sails and hopefully smaller crews to reduce costs.
