It was always like this. You never could long rest on the hags lair. I played since patch 3 and wasn't able to do that. So that is no news.
As for dumbing down the whole lair - no, just no. The whole lair feels nicely creepy and challenging, I really don't want that gone. And it isn't that hard, just challenging.
