At any rate, I'm going to stand by the position that "all unsourced edits can be removed" is not the same thing as  "All unsourced edits should be removed."  Unsourced edits that look very fishy should be reverted.  Unsourced statements that look potentially fishy should be given a {{fact}} tag, and then eventually deleted if no one provides a source.  Unsourced statements that one thinks are true should be met by just adding the unreferenced tag at the end of the article.
