doveadm neglecting to exit in failure?

cpssltest@cpanelssltest.org [/usr/local/cpanel]# doveadm -v expunge -u cpssltest -- mailbox-guid b8a359119e771b58484a0000a841250d savedbefore 365days; echo $? doveadm(cpssltest): Error: net_connect_unix(/var/run/dovecot/stats-writer) failed: Permission denied 0

^^ In the above, shouldn’t the “doveadm” command have exited nonzero to indicate a failure to connect?

Thanks!
