      • SERVER-54127: Retryable update by _id may execute more than once if intervening write changes document's owning shard
      • SERVER-103727: Improve the semantics of read operations using coll scan or _id index scan in the presence of concurrent shard key value updates
      • SERVER-103728: Improve the semantics of write operations using coll scan or _id index scan in the presence of concurrent shard key value updates
