This is true, but then because gattrib_csv also can also  produce a BOM 
the duplicate data doesn't become visible.  The duplicate data doesn't 
cause any problems with disk space.  With the information in every 
symbol, then if another instance is desired of a particular part in a 
new or same design, it is just a just copy, paste, reset the refdes, and 
all the distributor information is copied with it. Then when gattrib_csv 
is used to generate the BOM only missing information needs to be 
imported back into the schematic.  Entries are only broken out to their 
own row in the table if they posses an attribute exposed by the filter 
that is different from an existing row.  Thus one edit in a single row 
in LibreOffice can update the attributes of every member of that type of 
component.
