Wonders are for all civilizations and early ones may need some modders' love most
. Because you're going to see them in every game.
UU is another approach and I think that they should be designed later, with as much seriousness and dedication as possible to make civilizations distinct not flavor-wise only, but gameplay-wise too.
Edit: I was ninjad with a different opinion. Well, I think because they are "more important", it means that there should be more time dedicated to their design rather than a strict implementation. Start a few brainstorming threads.
