The points at which the game transition between acts seem a bit arbitrary (mainly for Act I to Act II), and I don't see a narrative or mechanical reason to lock us out of previous maps and quests. As far as I remember, previous Baldur's Gate games didn't have this kind of points of no return. Why do you think they did it? Do you like it?
I used to enjoy participating in book clubs (be it in person or online), but between emigrating, the pandemic and life changes I haven't been in one in quite a while. What about you? Do you enjoy reading groups? If so, in person or digital?
