> In Scala, we prefer sealed traits over Enumeration since the former gives you exhaustiveness checking. With Scala Enumeration, you don't get a warning if you add a new value that is not handled in a given pattern match.
> This Jira tracks refactoring enum [FeatureZNodeStatus|https://github.com/apache/kafka/blob/fb4f297207ef62f71e4a6d2d0dac75752933043d/core/src/main/scala/kafka/zk/ZkData.scala#L801] from an enum to a sealed trait.
