> Using Kafka's public APIs to get metadata regarding the non-reassigning replicas for a topic is unreliable and prone to race conditions.
> If a person or a system is to rely on the provided metadata, it can end up {color:#202124}unintentionally {color}increasing the replication factor for a partition.
> It would be useful to have some sort of guardrail against this happening {color:#202124}inadvertently.
