    Unfortunately, this would break the non-sql clients. Looking more into Hive's behavior,
it currently does:
    * lowercases all column names
    * preserves all struct field names
    
    That makes a mess. I'd propose that we add a new option for readers that makes schema
evolution lowercase everything and Hive should always set that option.
