The `serviceType` for a managed GatewayClass will default to `LoadBalancer`, which is appropriate for most deployments to managed Kubernetes cloud offerings (EKS, GKE, AKS) - other deployments, such as to a [kind](https://kind.sigs.k8s.io/) cluster, may require specifying `NodePort` or `ClusterIP` instead.
