Reporters SHOULD rate limit the number of failure reports sent
to any recipient to avoid overloading recipient systems.
Why would reports due to a mail loop be more of a problem than due to
some random spammer sending a lot of fake mail, or (real life) your
users send mail to mailing lists with thousands of subscribers? Rate
limit your reports, don't worry about where they came from.
