Configuring Kafka as the default broker class

[wuminorb]

Problem
According to the doc, only ChannelBasedBroker and MTChannelBasedBroker are supported. Is there a way to set Kafka as the default broker class?

Persona:
System operator

Exit Criteria

apiVersion: operator.knative.dev/v1beta1
kind: KnativeEventing
metadata:
  name: knative-eventing
  namespace: knative-eventing
spec:
  defaultBrokerClass: Kafka
  ...

Time Estimate (optional):
Not sure

Additional context (optional)
As ChannelBasedBroker and MTChannelBasedBroker are not recommended for production. We want to have this to support the production deployment.

I am now looking for the correct way to configure kafka for eventing. Do you know without operator, how do you configure it with knative eventing?
I need to map to the CR to see if it is possible to configure.
