Bad examples you can find all over doa2 and based on some interviews with Larian BG3 is on the way to make the same mistakes. The official plan right now for companions in Baldur's Gate 3 is that somewhere between the end of act 1 and the beginning of act two you will have to "commit" to a party. Which means that you will have 3 party members with you for the rest of the game, while the other 2 ( and probably more) will be gone. This is artificially creating replay value. Of course, the same was true in dos2, and there it was even worse, since it actively sabotaged the story. I can talk about it more if you like.
I remember my lone wolves run with a mate where we recruited nobody and had the entire character roster show up undead later just to scold us for "betraying" them. Good times. We fried them all.
