Replace it with the {{more sources}} tag, I think. I find articles which use {{unreferenced}} despite having references very irritating, because {{unreferenced}} is only for totally unsourced articles. It's especially annoying on articles with a lot of references, but one or two totally unreferenced (And sometimes just sparsely referenced) sections.

I got into a bit of a battle on this, where someone referenced a single comment about another slightly related topic within an article and removed the unreferenced tag--the sentence was added, copying the reference from another article, solely to remove the unreferenced tag from a crappy and unreferenced article. I don't think this is what you're talking about, but there are times when there are references and the tag should remain. Still, I don't think unreferenced tags are as important as adding references.
