Your definition of "most" is very intriguing. Well now you know there isn't going to be any, so no more "harm" done. And if people read/ask they will also know. To get your hopes up on a few lines of dialogue is a bit presumptuous, the characters say a lot of things when they reach their highest dialogue level, but that doesn't mean all of it will be actual content in the game.
Also if you reach the point where you get this dialogue, then you obviously have other interests that brought you here in the first place, which is obviously going to be the primary focus.
