Shrines in caves, the Overworld, Nether, and End

Games such as Zelda: Breath of the Wild have these dungeon like puzzle rooms called "Shrines" that you can find all over the world where after you beat the shrine you can get some good loot and I was thinking that'd be a great idea for Minecraft, having little puzzles you can come across when traversing through the places mentioned in the title that are made with blocks you can't break in survival so the player can't just cheese them where you can find some potentially good loot such as enchanted tools, enchanting books, minerals, and/or OP foods. Obviously they would have to be a name other than "Shrines" to make them a bit more original.
