Yeah I realised that a while back but I have a few ideas. Just because I CAN have as many companions with me as I want doesn't mean I will: there are some quests out there where having the whole crew around is not really necessary, therefore I can just say they're all taking a break somewhere or sorting out their own problems etc. Hell, I can even use them to skip some uneventful quests e.g. collecting debts (why only have the Courier do all the work when everyone else can pitch in some effort?).
