Review Comment:
And regarding
> why these tests only work with Spark2 and Spark4.1?
I found this issue: https://issues.apache.org/jira/browse/SPARK-51290 for
allowing partial column writes.
This fills default values for missing columns in DSv2 writes which seems why
our tests pass on 4.1
And I have a question: I noticed this was enabled in Spark 4.1. Is there any
chance this could be backported, or is it considered a new feature?
