There's another, bigger issue with _user and _group.  A daemon that
needs to, say, open a privileged port can't use _user and _group,
because it will start as that user / group instead of starting as root
and then dropping privileges on its own.  This affects named in base and
varnishd (and probably others) in ports.  There should be a way to tell
rc.subr that the daemon will handle _user and _group itself.
