Yicong Huang resolved SPARK-58016.
----------------------------------
    Resolution: Won't Do

Not reverting. We will fix forward to reduce the regression via 
https://github.com/apache/spark/pull/57099, 
https://github.com/apache/spark/pull/57104, and 
https://github.com/apache/spark/pull/57105. A complementary fix is also needed 
in the Apache Arrow (PyArrow) community. Revert PR 
https://github.com/apache/spark/pull/57094 is closed.
