Does operator support gateway API

• Installing Knative Serving using YAML files
• Install by using the Knative Operator

The YAML installation method seems to support the gateway API, but is the operator still not supported? I specified data.config.gateway in the KnativeServing resources, but it doesn't seem to be working.Here is my configuration:

apiVersion: v1
kind: Namespace
metadata:
  name: knative-serving
---
apiVersion: operator.knative.dev/v1beta1
kind: KnativeServing
metadata:
  name: knative-serving
  namespace: knative-serving
spec:
  config:
    domain:
      example.com: ""
    autoscaler:
      max-scale: "20"
    network:
      ingress-class: gateway-api.ingress.networking.knative.dev
    gateway:
      external-gateways: |
        - name: envoy-gateway
          namespace: envoy-gateway-system
          service: envoy-gateway.envoy-gateway-system.svc.cluster.local
      local-gateways: |
        - name: envoy-gateway
          namespace: csghub
          service: envoy-gateway.csghub.svc.cluster.local

When is the operator expected to support the gateway API?
