But I understand YMMV. While node information message can be interesting at times, since they are only supported in BSDs and can only be used when on-link, it's not a debugging mechanism you can rely on. As a result of that, my 2cents would be "disable them by default". If in your particular setup woul'd benefit from them, you can always override such default on system installation.
