I agree that duplicate code is annoying., but there's another concern. The `Endpoint#listenerName()` method returns an Optional object. If we utilize Endpoint on the server-side, this could lead to frequent calls to `listenerName().get()`. To avoid duplicate code, we might consider using the record class to streamline the handling of `Endpoint` on the server-side. I've noticed that `Endpoint#listenerName` does not appear to return `Optional.empty` in the current implementation. I haven't been able to find any scenarios where an `Endpoint` is created with a null listener name. Therefore, I suggest filing a follow-up (a smaller KIP) to revise the public APIs and remove the Optional type for `listenerName`. This change would also allow us to eliminate the duplicate class as suggested by @mimaison. @mimaison @TaiJuWu WDYT? -- This is an automated message from the Apache Git Service.
