I think there's no need for that as it normally becomes collectible if an item physically is limited. You don't have to put that as an NFT because you can keep or buy it as is. That depends on the manufacturer or maker or seller of that item if it's limited and that's why most NFTs are worth it because they're limited-made. Maybe, someday in the next years that there will be a physical NFT that they have to integrate because they're looking at it as another trend to adapt.
