Review comment:
I think this is a bug fix. A V2 catalog can return a function that's
non-deterministic, while without the fix Spark can treat it as deterministic
and apply related optimization rules (e.g., constant folding), which could
cause correctness issues.
Since this is already in Spark 3.2.1, I don't see much benefit of reverting
it and re-introduce the correctness issue.
