Not to say that it's a great idea, and our FC certainly doesn't do it, but another - possibly more reasonable - use of the function would be for trial members. Like if you are a company that accepts a lot of people, but want to make sure they will fit in with the group before actually "admitting" them. Just fully restrict them from the FC functions in general (including housing) basically turns the FC into a glorified Linkshell. I suppose you could always just have a Linkshell for testing new members, but having an entry rank would probably be easier. Hard to justify though.
