If this were the _first_ capability we are adding to the system, the above makes quite a lot of sense, but I do not recall any existing capability that can be configured this way. How would one deploy a set of servers that gradually start allowing fetching unadvertised but reachable commits, for example? I am not saying that the "I'll accept if asked, but I won't actively advertise" is a bad feature; I just find it disturbing that only this knob has that feature.
