That's... a bit excessive.
What they were doing for 14, and or are doing for 14. Is a way to allow food items, medicines, temps to not use up inventory space. As well as something to do with equipped items and what not.
They also, currently allow bazaar to be a separate inventory in a way. Allowing you to put items up for sale, for reasonable or unreasonable prices. Either way, they do not remain in your main inventory and you're able to leave them there.
So there's a lot of ways they could look into this, and maybe make a inventory slot very much like they do for medications in Abyssea. This time however for things like food, ninjitsu, ammo, who knows. However, it's just another one of those things that would be beneficial. Although not as beneficial as being able to utilize your inventory on the field regardless of inventory you're looking into Mog Sack/Satchel/Main.
