> !image-2025-07-04-19-05-51-900.png|width=1065,height=489!
> seen in KAFKA-15141, the corresponding classes
> IncrementalFetchContext/DelayedProduce/SessionlessFetchContext have been
> processed, but I think a better approach should be to optimize the trait
> Logging, we can introduce a static Map object to cache the duplicate loggers
