I don't see how the option of eating food is breaking someone's immersion, if it a an option. That means you don't have to use it if you don't feel like it. I just don't think it's fair that a vocal minority gets to have a say on how everyone plays a game. That's gatekeeping.
This is not about breaking the game or options, more about the rule system. BG3 was declared to be a DnD game made according to the rule-set of DnD 5e. But Larian instead mixed two systems - 5e and their own from DOS. DOS is good for their games - all this goofiness, funny moves, things like gulping in pig's heads - funny and creative, but this is not DnD and, most importantly, it contradicts and negates many DnD rules.
Should they say "we are making BG3 but with our system" - they could do whatever they want. But the deal was "use 5e rules", so, it is expected, that the game will follow 5e rules.
The rules 5e are not set in stone, even WOTC have said this. They are meant to be a guide, the DM is still the final say on rules. That's why homebrew rules exist.
