I'm not a big fan of setting these flags -- I fairly frequently run into problems when I installworld an NFS root on the NFS host, then try to work with it over NFS from the NFS-booted system, as the flags can't be removed via NFS. They don't offer a security benefit as-installed, and perhaps offer a benefit with respect to preventing people from shooting themselves in the foot (or perhaps not).
