I guess this is the kind of stuff that may happen when a dev team is rushed and has to put out a game too soon than they should. These conditions may imply omissions. ttlan, you must understand that the story of this game has been corrupted. They had to rush-it, so the story basically lost some details. Furthermore, a dev team has many ideas, and has to discard some of them in order to get a story that makes sense. Now since they left some (a lot of) unused content and no notes on the usefulness or "cannonicity" of them, we should assume that the official and only version that is official is vanilla. Slight problem: like so many of us, you think the game lack a little something and that by restoring some parts of the game, it will be easier to understand, have more depth to-it. The problem is we can't be sure what they really thought was going to happen. Furthermore, we have to consider this game was not the idea of a single person, but of many a one. So even they must have encountered some divergent opinions.
So here's where TSL RCM comes: they restore as much content as possible but try at best as they can to preserve the intentions of the authors, without a lot of informations of what should have been. What's more, they have to judge what makes sense and what doesn't. The informations you seem to contest are on the same nature than that of what the original team must have discussed, but since this is no official team, but some great modders that give their free time to make a great game even greater, I think we should thrust their judgment when they have to decide if something is worth restoring or not. If any of us disagree with what they are restoring we have 2 options: do not download/install the mod and keep to vanilla or try to be as proficient modders as they are and modify what we think should be.
