There will be a lot of factors constantly perturbing the trajectories, so lacking the ability to take corrective actions should be out of the question. Unless something happens too close to the point of contact, I expect the situations to be calculated and compensated for. Also, that tiny window that you talk about doesn't actually have to be that tiny. There can be engineered a string of potential contacts with multiple tethers on slightly different orbital altitudes to lower the risk, and for fungible cargo like fuel or other kind of supplies, that may fall be within the acceptable risk margin. Of course, people and other high value cargo can be serviced by other means if necessary.
