What the wiki says is useful, it's the tag name that is just really counter-intuitive and dooms itself to this state.
I'm just not sure about the most efficient way to go about that rename though, the tag needs to be deprecated anyway, but either temporarily until it is completely gardened and renamed properly, or until it is gardened in a way that lets it then be aliased to leg up while a new tag is made to take the posts the wiki is currently aiming at.
