   So, the best I can follow, this looks good, but there's one issue I'm not clear on.  If we're just expanding the projection to include possible matches (e.g. equality case), doesn't this cause a problem where the partition values are joined in (i.e. not materialized in the data like converted Hive tables)?
   
   I assume we don't have a way to correct for that case since the recorded transform is incorrect and we cannot materialize the correct data to filter later?
