I've used drones in a couple of situations where there is no player character. Inserting drones into the buildings becomes fiddly, as it must be done with requester chests and inserters. You can't really controll how many are inserted, and you have to leave space in the build for a box and arm.
Would it be possible to have the transport drones inserted by a logistics request, similar to inserting modules or putting fuel into a blueprintted locamotive? Then I could actually build these things from god mode reliably.
