The problem with session zero imo, is that the vast majority of campaigns you play with strangers/non-close acquaintances only lasts 2-3 sessions in my experience. Dedicating one session to just setup is not really feasible. If you're playing a long campaign, you're playing with friends and you probably already know each other well enough to know what flies and what doesn't. I just don't see how it's a good solution for anyone, but all human interaction is messy, and the problem they are trying to solve definitely exists, so they couldn't have just ignored the problem, so they offered a one size fits all solution that's ideal for probably no one.
