Abhi Yeah, but that doesn't mean they couldn't add a way to get to it later, or to come out from it.
I did think it might be something someone just didn't think to deactivate. There are plenty of examples of that concerning movable objects. City Beach, for example, has shopping trollies (carts) that light up when hovering over them, but you can't move them. Since they are sometimes movable in other Mines, then removing the lighting up aspect of them might have been something which was neglected. Or it could have been purposefully kept to make some players think they could be moved, or needed to be. I just see things like that and keep all possibilities alive until I have something to discount any of them.
