Old Villages should be archaeological sites

Always wanted some representation of old pre 1.14 villages in the modern game and just thought of this one, making the pre 1.14 villages as archaeological sites, you can have a rare chance of stumbling onto the roofs of the old houses poking just above the ground to indicate the archaeological site, you can possibly get as a armor trim the “old days” trim which will make all the armors including netherite and copper into the old armor style and textures and a shard that can be a villager or showing the formation of the illagers. And for blacksmiths the lava would had hardened into obsidian but you can still find the old chests with pre 1.14 loot tables in it.
