[~Penglei Shi] Kyuubi community has a Spark extension to support similar stuff
about `finalStageConfigIsolation`, see docs

> Support repartition expand partitions in AQE
> --------------------------------------------
>
> Key: SPARK-35725
> URL: https://issues.apache.org/jira/browse/SPARK-35725
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.2.0
> Reporter: XiDuo You
> Assignee: XiDuo You
> Priority: Major
> Fix For: 3.2.0
>
>
> Currently, we don't support expand partition dynamically in AQE which is not
> friendly for some data skew job.
> Let's say if we have a simple query:
> {code:java}
> SELECT * FROM table DISTRIBUTE BY col
> {code}
> The column of `col` is skewed, then some shuffle partitions would handle too
> much data than others.
> If we haven't inroduced extra shuffle, we can optimize this case by expanding
> partitions in AQE.
