I think the long rest is fine, given that the background now changes depending on where you are.
I have had only one or two long rests so far, but the latest went like this: We were standing on on a rock peak, near the place where the sirens nested. The peak had just enough space for four people to stand on. The long rest button teleported us to a totally different place, which looked very much like the standard camping site from patch 5. After resting we were instantaneously back on the rock peak. So if the plan was to convey the idea of camping in situ, it failed.
