In the case where the rbdmap utility is invoked by systemd (i.e. to map RBD devices on system startup and unmap RBD devices on system shutdown) [1], I would think the current unmap-all behavior is desirable in much the same way that only filesystems listed in "/etc/fstab" are mounted at startup but all filesystems are unmounted at system shutdown.
