As far as spacing out companions, I do get why Larian would want to get all the companions introduced quickly. The later you introduce a companion, the less time the player has to get invested in them.
Don't forget that they are all playable and can be picked as your character (or your companion character). So like D:OS2 all companions are tied to Nautiloid. I do wonder if they will revise opening before 1.0 to include more future companions, like D:OS2 did.
