      SERVER-31242 describes how we should apply the original projection to findAndModify when retrying the operation as part of retryable writes project. However, avoiding writing the full document into the no-op oplog entry rather than just the necessary fields would keep size of the oplog small, and may make it unnecessary to do the work described in SERVER-31242.
