Seriously, great choice. Not being able to experiment with party compositions, experience companion stories, mutual interactions and banter in a single run was one of my biggest worries. I'm sure you've made a lot of people happy with this Larian, thanks for listening!
I fully agree, thanks from me as well!
Just to be clear, I'm very much in favour of "soft" party limitations, such as companions leaving you when their approval hits rock bottom, you act in a way that severely conflicts with their principles or they come to blows with another party member for understandable reasons.
This has never happened in any of my games yet, but I like that it is possible, it makes sense.
