I think I would label this as more of a weakness in how the user who cares about encrypting the document is going about it. Can't you just save the original file to an encrypted volume (such as with TrueCrypt), and shouldn't you make sure that you're not saving any sensitive data in plaintext to any unencrypted volumes?
