considering the first flight where they were rewriting code while it sat outside the station; reconfigured the LIDAR on the fly; I would put it down being overly cautious, maybe a bit of fear? Let us be honest, with all the difficulty of getting that module into space docking isn't that big of a deal. If there were no people on board no one would care.
Plus I have to ask, if a thruster suddenly misfires or goes haywire who is going to be faster? In Apollo days I would put odds on the astronauts, today - I am betting on a computer. We will sooner trust a car to drive itself before we allow a freighter to dock with a space station.
