Yeah, there's really no need to complain about it at all. It doesn't mess up the original films because it doesn't affect them. And I don't think most people noticed that they weren't in the prequels. I sure didn't. I don't think it would have made any difference had they been in there (although, like I said earlier, it just doesn't feel like it belongs in the prequels, but maybe that's just because they weren't there to begin with), but it's a nice thought that Lucas would want to save that for the OT. I'm still not sure why he'd want to save that, though, when he tried to re-use other things for nostalgic value.
