However, barring that [...]
I think we should remain "ambitious", and keep asking for a party-based RPG that feels somewhat-decently like it is a party-based RPG. (And not like a game designed for a single adventurer, but in which the option to have followers/companions for us to use during combats was later added.)
If our companions are there during a cutscene and can interject, they should do so.
If our companions are there during a cutscene and can comment on it afterwards (yellow exclamation mark on their head), we should be able to discuss what happened in that scene with each of them afterwards.
(And while I'm at it, I guess it's hard not to mention that if our companions are there during a cutscene and can make an Ability Check better than we can, we should be able to have them do it. Though this is starting to drift away from the original topic.)
Also, I hope that the toilet chain will go away entirely. If that terrible system is to remain in the game, I'd much rather have the particular order of companions in the chain not matter at all.
... Unless we can have party formations. But then I'd want the order to matter only for party formation, and not have to switch order when I want to explore story/dialogue content.
All in all, I feel that this idea of using the chain order would be essentially trying to pile up bad ideas on fundamentally-bad systems in order to try to smooth things out a bit, instead of actually addressing the fundamental problems. And I'd vote for making the fundamentals better.
