Yes. Because the HighWatermark field is tagged and ignorable, all version 18 FETCH requests can be serialized to versions 17 requests. We still need an MV version because the replica fetcher restricts possible version values using the MV and FetchRequest.Builder#forReplica builder. Thanks, -- -José
