5e Tony hut goes much further than that though. I watched a group of level 5 PCs seriously start to argue that they were safe from a kinda blind ancient/great wyrm dragon they knew had a grudge against them in Rhine of the frostmaiden the other day even though it was physically knocking on it. A second player actually suggested shooting at it with ranged weapons "from the safety of the dome" rather than trying to run away too.It's mostly just another way the designers tells you that the exploration part of the game isn't fun and you should bypass it with some minor resource.
Also outdoor exploration being deemed badwrongfun doesn't mean that it has no place in a game even if tiny hut was only useful for that
