      Currently, mongos can't attach the txnNumber from a request's operation context in the sharding_task_executor (like it does with the session id) because it can re-use the same operation context that sends the client's actual request to send metadata operations to the config server (e.g. implicitly creating a sharded collection through the ChunkManagerTargeter). If this could be resolved, mongos could blindly forward txnNumbers to mongod and let mongod validate them, instead of needing to do it itself.
