The only use case I'm aware of for invalidation is 2nd level cache and I don't think that needs a remote cache, Galder wdyt?

I don't know if 2nd level cache actually uses ClusterCacheLoader, but it could definitely use it without exposing the cache through HotRod.

this makes me wonder: what would be the case in which one doesn't want to use state transfer for a distributed/replicated cache.

In replication mode, if the cache has a huge (non-shared) cache store, some users may prefer to disable fetchPersistentState and rely on ClusterCacheLoader instead for less frequently accessed keys.

I don't know if it ever makes sense to use ClusterCacheLoader in distribution mode, since it always sends the ClusteredGetCommand to the entire cluster.
