Hi, I'm curious: Why does Paimon have its own Flink-CDC based 'sync actions' <https://paimon.apache.org/docs/0.8/flink/cdc-ingestion/overview/>, while Flink-CDC itself has a built in Paimon <https://nightlies.apache.org/flink/flink-cdc-docs-master/docs/connectors/pipeline-connectors/paimon/> pipeline connector support <https://nightlies.apache.org/flink/flink-cdc-docs-master/docs/connectors/pipeline-connectors/paimon/> ?
Thanks, Andrew
