That's a good way to have all of the spam you forward attributed to your own domain and hurt it's reputation in our system. That applies to using SRS too. If you don't forward spam, or don't rewrite things you think are spam, rewriting is less harmful. I realize that Gmail auto-forwarding does indeed rewrite the mail from, but I'm going to go with we do a good enough job of spam blocking, and also our forwards are not a high percentage of the gmail.com mail, so it does actually meet the suggestions.
