Not only I'm not too fond of the "commit to the initial choice" approach.
I'm even less fond of the idea that all companions will have to be introduced in the beginning AND be "playable origins". That is bound to severely limit their number and variety, not to mention the chances to surprise us later in the story with new potential allies.
This is something that I agree with, I personally dislike the play as companion options that they want to implement in BG3, it was fine for their other games, but BG puts a huge focus on the world being filled with adventurers who can join in and help you at any moment.
