No, you must create the skeleton hostgroup as below. It's not a bug,
that's how it's designed. It can't auto-create it as the other required
hostgroup element, alias, would be unknown.

define host {
        use                     generic-host
        host_name               tnops-redacted
        alias                   Redacted - 4774
        address                 redacted
        contact_groups          tnops
        hostgroups              tnops-williamson,all-middle-tn
}

define hostgroup {
        hostgroup_name  tnops-williamson
        alias           Williamson Tennessee
}

define hostgroup {
        hostgroup_name  all-middle-tn
        alias           All Middle Tennessee
}
