Yea, it's really rather about https://github.com/apache/spark/pull/25022. But I have to say there are still multiple tasks to fully support interval. For instance, we should map relevant language-native types into internal in Python and R as well. See [SPARK-28493](https://issues.apache.org/jira/browse/SPARK-28493) and [SPARK-28492](https://issues.apache.org/jira/browse/SPARK-28492). Also, we should consider about mapping R <> Arrow, Pandas <> Arrow too.
I think we should officially those internal related features are experimental and highly unstable to alleviate the concern.
