I think the distinction is very, very important. Bug means that something that was intended to be in the game is broken. Lack of reactivity can certainly be detrimental, but you are essencially asking for more content and Baldur's Gate3 is already a very large game, that's been developed for many years.
I said SERIOUS scenes. I find it hard to believe that Larian has never planned for any reactivity in some of the most important scenes, while developing this game. If they didn't - well, their mistake that should be corrected. I'm not asking for minor scenes reactivity. I'm sure, most of them are just bugged. Like a lot of scenes of Spawn Astarion are currently bugged. For example, his scene after Tav cheats on him with Mizora just doesn't trigger, but it's definitely already recorded - there are voicelines of it in the game's files. So this is in no way the same as "writing, recording, animating and testing an uncounted amount of cutscenes ". I don't ask it. I ask to fix what is broken, essentially.
Also, a lot of bark voiced lines are also already there - you can find them on YouTube, they just never trigger.
P.S. That said, I think there is definitely one scene which they should record again - the big Durge moment, when your companions and especially your LI don't care at all that you
just died
This is the one scene which should be changed significantly. But still, I bet, it's the only one. Or one of a few ones.
