This interface seems to be added as part of https://issues.apache.org/jira/browse/FLINK-32514 / https://cwiki.apache.org/confluence/display/FLINK/FLIP-309%3A+Support+using+larger+checkpointing+interval+when+source+is+processing+backlog
The FLIP indicates that the changes should be backward compatible, but that appears to have not been the case
