Review Comment:
Thought: haven't looked but maybe we could push this logic down to
ManifestEvaluator, return "ROWS_MIGHT_MATCH" match for any partition comparison
involving a partition field that has become VoidTransformation (ie, removed in
V1). (I am thinking this case of querying removed partition field should only
affect metadata tables primarily).
