Swash is suggesting adding the name of the next-over room to what you already do see over there. Which isn't much. It's more in some places than it is in others, depends on the room. If there are vehicles or people (characters), and the seeing conditions and your perception allow it, you could see them. You may see what is really a description on the exit itself, but that isn't truly an attribute of the next room. You never see the name of the room, unless you walk over there.
Which is exactly why I'm not personally too wild about this idea. Just as Swash says, it would influence players' decisions. Not for the better, I'm convinced. If there's an exit which truly has inadequate information on it and people are unfairly losing their characters' lives or something by skipping cluelessly through it, there's a way to remedy that which doesn't involve retrofitting the entire MOO in a way that probably reveals too much in a lot of places. Not all. But some. Some important ones.
