Great question, I don't know. However, at least in my case, I wouldn't mind the source data always overwriting the local data. In fact, that's the way it works now when loading a newer snapshot, the local db is dropped and then re-built from the snapshot

Thinking about the developer experience though, when loading a snapshot manually, the dev knows they are overwriting their local db. However, if replication happened automatically/continuously on the background, it could lead to some really confusing/annoying behaviors
