Quorum without read repair

A Dynamo-style store uses sloppy quorums and hinted handoff. Why is anti-entropy/read repair still needed?
Options
  1. 1To compress data across the replicas so that anti-entropy reduces the bytes replicated each day
  2. 2To reduce the write latency by batching hints so that handoff completes in a single round trip
  3. 3To encrypt the replicas so that reconciliation can verify integrity without decrypting any data
  4. 4Because hints/replicas can still diverge after extended partitions, and background reconciliation merges them to converge
