the only question is whether delivery servers, which need to add a Return-path of their own should be required (presumably with a SHOULD, possibly a MUST) to verify that there are no Return-path header lines present, and removing them if needed

2822upd-01 still says:

  trace           =       [return]
                          1*received

That's at most one <return>, not more.

Uh, no. Even in 2822, it was:

fields          =       *(trace
                          *(resent-date /
                           resent-from /
                           resent-sender /
                           resent-to /
                           resent-cc /
                           resent-bcc /
                           resent-msg-id))
                        *(orig-date /
                        from /
                        sender /
                        reply-to /
                        to /
                        cc /
                        bcc /
                        message-id /
                        in-reply-to /
                        references /
                        subject /
                        comments /
                        keywords /
                        optional-field)

That's one <return> per *set* of <trace>. 2822upd includes <optional-field> up with the <trace> as well.
