A downgraded node could find an oplog entry containing multiple statement ids through the retryable write state persisted in this collection. To remedy this, one potential solution is on setFCV downgrade, we traverse through the config.transactions collection and remove any entries referencing a retryable time-series oplog entry. An alternative is to set a 4.4 downgrade floor, and to teach 4.4 to parse these new oplog entries.
