The paper is quite important - it's the first paper about the production usage of an algorithm similar to Single-Decree Paxos. 1) The atomicity usually isn't a problem, it can be added on top of the sharded storage with 2PC, RAMP or Percolator transactions, or with Sagas. 2) With Raft you have to implement log compaction and snapshotting, with Bizur and Single-Decree Paxos it isn't the case
