It's likely that we will see these things in the future, but like many things they were just left out in the interest of getting the game out on time. If you go to FFXIVPRO's item search feature, it will bring up things like Woolen Hats, Linen Doublets, Darksteel Harness, Gold Sabatons, Wyrmskin Thighboots... these things are in the .DAT files, but not yet implemented in the game. It's possible we will see them in future updates, though probably not until after the Devs have attended to more serious matters.
