I'm just gonna voice my personal opinion on the matter and say that question doesn't really need an answer. Obviously if the creators of a game can give a good, narratively satisfying answer that's the better course of action, but at the same time it's a game, there's a suspension of disbelief inherent in the buy-in of the game. Am I alone in thinking this issue really isn't a big deal? If it matters to you then okay, I obviously want you to have games that line up with your sensibilities, but I genuinely am surprised that so many people see companions hanging back at camp due to party size limitations as an actual thing worth remarking on.
