From what I've seen, Zipline is being run between managed locations, rather than delivering to random points on the map, but I could be wrong about that, I last read about it a couple of years ago. Also, like a lot of solutions, this doesn't have to be perfect, it just needs to be better than the alternatives, which Zipline appears to be in the places it is being used.
