Serverless 1.4.0: When creating Knative Serving (obsolete) CR object via Webconsole, this YAML template is generated:

apiVersion: serving.knative.dev/v1alpha1
kind: KnativeServing
metadata:   name: example
  namespace: knative-serving
spec: {}

The problematic part is "name: example"

While arbitrary name works, the template should be consistent with new Knative Serving CR, which uses "name: knative-serving".
