      This copy operation can be replaced with a mutable reference to the container of replication operations.

      Compare with this usage of TransactionParticipant::retrieveCompletedTransactionOperations() in TransactionParticipant::prepareTransaction()|https://github.com/mongodb/mongo/blob/2b958166154c99dc554591d57ce44caee35cb446/src/mongo/db/transaction/transaction_participant.cpp#L1600].

      Storing a mutable reference to the completed operations is preferable because the caller is responsible for clearing the in-memory operations using clearOperationsInMemory. Additionally, the OpObserver interfaces are declared to accept a pointer to the vectory of ReplOperations.
