why does product inventory page hide DELIVERED serialized inventory?

[Si Chen]

Hi,

For some reason serialized inventory in the state of "DELIVERED" do not 
show up in Catalog Manager's Product > Inventory tab.  Looking at the 
code it's fairly obvious why:

$ vi 
applications/product/webapp/catalog/product/EditProductInventoryItems.ftl
   <#list productInventoryItems as inventoryItem>
      <#if showEmpty || (inventoryItem.inventoryItemTypeId?if_exists == 
"SERIALIZED_INV_ITEM" && inventoryItem.statusId?if_exists != 
"INV_DELIVERED")

But why is it done like this?  Is there some design reason why 
serialized inventory in the DELIVERED status should not be shown, but 
all the other status codes are shown?
