Personally, I like the idea that they are putting into place, firstly because it makes the game more in line with the 5th edition design, resting requires you have enough food, like rations, to have the effects of a rest, and in 5th edition not having enough food to rest comes with penalties though. Still, I don't know if they plan to implement an exhaustion system in BG3. Other games like Pathfinder Kingmaker already used the idea of requiring food to rest, but characters could hunt for food in that game if they didn't have enough. I'm not sure if they will expand more on the way long rests work in future patches, but currently, I'm pretty happy with the announced changes and look forward to trying them out.
