There's no fixed party in the game, you could have one of several origins (or even no origin) and several companions with different origins, so that's another little obstacle which would complicate adding campfire chats.
That's pretty pessimistic. It's like Larian saying, "We heard your feedback about wanting a deeper story with more interesting characters, so we we added complex origins to the characters. The only catch is that they can never do anything, and have no role in the story."
I'm not fussed about camping, but banter should be practically mandatory.
