Indeed.  I check DMARC on all my incoming mail, but it is unlikely
that I will ever get around to sending reports.  I am not expecting
the Protocol Police to break the door down.

More to the point, IETF standards tell people what to do if you want
to interoperate, not how the document's authors might wish the world
were different. You can obviously implement all of DMARC processing on
inbound mail without ever sending a report, so in this place MUST is
simply wrong.
