Indeed.  I recently had to field a complaint that invoked an analysis
by https://dnschecker.org/domain-health-checker.php as being related
to problems someone was seeing.  That report didn't show errors, but
of the eight warnings that it issued--and that the reporter thought
needed attention--they were either incorrect, irrelevant, inscrutable,
or simply wrong.
