I've thought about this before, but I never said anything because I'm torn about it. I do enjoy movieverse stories - there are a few at ff.net that I am following. On the other hand, I love the contained little universe we have here, and having a section for non-L&C Superman fics might eventually turn the whole forum in a direction we don't want. So I'm completely on the fence.
If the admins do decide to create a new section, I suggest that instead of "Superman Returns", it should be "Superman in other media", like on Zoom's boards. That could cover the movieverse, Smallville, the comics, etc.
