I suppouse it's possible to restrict cruisers and above from using it, if it proves to be problematic for the server.

Being allowed to move only to certain areas would only consolidate their status as activity hubs, while other regions stay dead. That's why imo it should work with all neutral-dockable and allied bases; if people want pew in Magellan, they jump straight to Magellan. If someone organises convoy he jumps straight to RV point and goes on with activity right away.
