   > Not sure if it's a significant thing, but a Table can easily modify schema 
metadata whereas a recordbatch cannot (I'm also not sure if there's a reason 
RecordBatch doesn't have ReplaceSchemaMetadata).
   
   I think that is just a gap in utility APIs.  `ReplaceSchemaMetadata` isn't 
really modifying the table.  It's creating a brand new table with the new 
metadata.  You should be able to do the same thing with record batches.
