I suppose if the second scenario is correct and the bureaucracy lasts 10,000 years into the future there's not really any harm in having developed the signage anyway. But on the other hand, if we just assume that the knowledge will be passed on via bureaucracy or some other means and don't develop the signage and then those methods of transmitting the knowledge fails, it could be bad for people in the future.
