I can see two sides to the argument. Yes, I do believe to some degree uniqueness is important to a game like this. It should have a homely feel, and you should be able to identify a particular \"craft\" by its creator. It shouldn\'t, however, devolve into a stew of meaningless gibber. One way to combat this is to only allow \"unique\" creations to established PC\'s who have achieved a mastery in their craft. Newbies in a craft would only be able to create what they have knowledge for. This would prevent a deluge of crafted items, but would allow a certain amount of creativity to come into the creation process.
