in my opinion should follow dnd5e rules.
Yeah. Problem is that it's not that simple. They have to program a way to limit resting like a live DM would. THAT is the trick. That's why we're endlessly discussing it.
A live DM would say, "No. You can't rest in the burning nautiloid after defeating 3 Devourers. You need to find a safer location first." A live DM would say, "No. You've triggered the hag side quest. You can't long rest until it's done. I might let you short rest, but no ;ong quest.". And a live DM would not make the hag so tough so that you needed to Long rest before fighting her so you could do the entire quest without needing a long rest.
The main issue with BG3 has to do with what also makes it so awesome. Freedom. You are free to trigger the hag quest but then free to walk away. You aren't locked into completing it. Same with all the quests.
So, the result of freedom is that you are free to trigger the quest and then long rest as much as you want. Why, because you are free to go in whatever direction you want. If long rest is locked, you wouldn't have that freedom.
That's why I think the best solution isn't locking, it's soft penalties. Trigger the hag and long rest. She's still waiting for you because it's a game to her, but now she's more prepared. Maybe she has minions now to help her whereas if you faced her right away she'd be alone. That is what I keep trying to say. Small, easy to implement consequences to discourage LR and encourage SR.
