Does nginx-gateway-fabric support RegularExpression type in HTTPRoute's HTTPHeaderMatch ?

Does nginx-gateway-fabric support RegularExpression type in HTTPRoute's HTTPHeaderMatch ?
I create a HTTPRoute with HTTPHeaderMatch's RegularExpression , but it doesn't work.

apiVersion: gateway.networking.k8s.io/v1
kind: HTTPRoute
metadata:
  name: echo-header1
  annotations:
    # konghq.com/strip-path: 'true'
spec:
  parentRefs:
  - name: nginx
  rules:
  - matches:
    - path:
        type: PathPrefix
        value: /echo
      headers:
      - name: "Cookie"
        type: "RegularExpression"
        value: "^tenantid=a.*$"
    backendRefs:
    - name: echo1
      kind: Service
      port: 1027

@Yelijah we only support Exact matches for headers. See the gateway compatibility doc for details on what fields in the spec we support.

Please feel free to create an issue requesting this support, and we will triage it during our next community meeting.
