Review comment:
I can see that there will be opportunities to vary the logic depending
on Spark 3 version to take advantage of new Spark 3 features. However, as you
remarked, that is out of the scope of this PR. Here we just want to support
building and running against both 3.0 and 3.1 and keep the logic the same.
