This is a proposal for configuring username as secret in KafkaClientAuthenticationPlain raised for strimzi/strimzi-kafka-operator#10823

Thanks for the proposal.

I do not think the username is secret and I do not think Kafka is treating it as such. It can show up in many different configs and logs. So I do not think this would solve all your problems.

But this idea comes up from time to time. If we decide that this is something we should support, we should definitely have consistency accross our APIs. So should we accept this proposal and its implementation, it should propose and implement this for all places where the username is specified. E.g. also for SCRAM-SHA authentications and so on.

I don't think these two exist anymore.

You should also provide more details on the planned implementation. You cover only the API, which is important, but there is obviously also the actual implementation behind it that should be covered.

Thanks for this proposal which makes sense but as Jakub stated we would need more details about the implementation and not only a higher view of the API.
