Remove Horse Armor from loot chests

It has always bothered me how Horse Armor spawns in structure loot chests when, thematically, it's never related at all. So I propose that they be removed from structure loot chests. Here's what I would do instead.

• Add Iron, Golden, and Diamond Plating to structure loot chests instead of the Horse Armors. They're generic and fit in anywhere – basically ingots (stack to 64), but only obtainable in structures.
• Make Iron Horse Armor craftable with 8 Iron Plating + 1 Leather Horse Armor, with similar recipes for Golden and Diamond Horse Armor.

Here's why I think this would be beneficial.

• As stated before, Horse Armor doesn't fit thematically with any structure. Adding an extra step would fix that.
• Horse Armor clutters your inventory very quickly in larger structures, especially Nether Fortresses – but Plating items won't.
• Leather Horse Armor would get another use!
• Mojang could use the Plating items in future crafting recipes as a way to encourage exploration.
