> The current type for directoryId field in ReplicaKey is Optional<Uuid>. The field is Optional.empty when the directory id is Uuuid.ZERO_UUID. This nice because if forces KRaft to handle the empty care differently.
> The issue with this modeling is that anytime KRaft needs to serialize the directory it does an explicit conversion to the zero uuid when the option is empty.
> It is possible that adding a type like DirectoryId could improve the user experience when dealing with the directory uuid.
