Probably this is a smaller part of a bigger problem with crafting.
Crafting a Plate Carrier Complete Set or Smersh Vest with Backpack attached is another instance of crafting issues however slightly different than getting back Pristine items.
I think that this minor flaw would only impact on those who try to craft Ghillies. To some of those players such flaw may become an exploit and a time saver (why search for pristine Burlap Sacks if you can create one from Damaged one easily).
