What DMARC reports is that somebody other than yourself is sending
email claiming to be you.  And there is absolutely nothing that you
can do about it.  So the question arises: What is the value in these
reports?

To tell those others (in the case of legitimate mail via mailinglists)
they are doing something wrong and mail redirected by said mailinglists
isn't getting delivered (or like with gmail "marked as phishing and put
into quarantine").

Also with increased use of DMARC (which I don't personally care for but
the BIG mail operators are kind of forcing it) there will be more
bounces from DMARCed senders to subscribed users which may result in the
mailinglist software to incorrectly unsubcribe those recipients.
