      Description

      Currently, the coordinator waits for all participants to ack the decision before returning the decision to the client.

      Once a participant with a prepared transaction blocks requests with a higher transaction number rather than return PreparedTransactionInProgress (SERVER-38028), the coordinator can return to the client as soon as the commit decision is persisted (with the user's requested writeConcern, including journaling preference).

      Note that if the user requested w:1 writeConcern, the decision may roll back after being reported to the client, but regardless all participants will apply the same decision.
