OP has the title wrong. It should have been a starwars reference.
And yes unique items for sale would be nice. Although I think the reason is they are going for grim realism and backwoods blacksmiths tends not to be secretly master enchanters. I see unique staves as more in keeping with the game world, maybe and expert level staff per magic school on each instructor in winterhold. As for weapons, an upgraded base weapon at the smith would also be helpful for those who don't take smith.
There are lots of reasons why a smith might have some unique, enchanted items. Maybe one smith in the entire game could be excellent at enchanting and a couple more could have low skill. They would be able to sell some enchanted things frequently and maybe have one or two properly unique items. Other merchants could have bought enchanted items, stolen them, or had the enchanting done for them. Additionally, not all unique items need be enchanted. It would be nice to see some oddities for sale around the province.
Morrowind did this really, really well. It was exciting to walk into shops because many of them had unique things, and you never knew beforehand if this would be the case. You could often see special items on display, so being a thief could be quite rewarding (although sometimes too easy). The shops in Skyrim, by contrast, resemble the ones in Daggerfall: they sell leveled dungeon junk at best.
