It also served to make Geordi look competent. Granted it was for dramatic reasons, but I felt the show often made him look less than competent. The movies, on the other hand, did a great job of it, I guess at the expense of any real character work with him (aside from him looking at the sunset in Insurrection, something that an episode probably would have made into a "B" plot).
I love the scene in First Contact when he's getting an engineering away team together, picking people, ensuring engineering is seen after, and issuing a request to check the environmental controls.
