Stackable discounts

They should add stackable discounts for villagers, for instance, by repeatedly zombifying and curing them, or through raids, to achieve massive price drops. This could even lead to a new achievement, or simply serve as a personal challenge to see how low you can get the prices. This feature used to exist in the Java Edition and should be brought back for both versions. If some people find it too unbalanced, there could be an option to disable it, solving that issue. Mojang removed it due to balance concerns, but an optional toggle changes things, allowing players to decide whether or not to unbalance their world. Personally, I don't view it as an imbalance; rather, it's a difficult personal challenge, getting those huge discounts without accidentally killing the villager is no easy task. Plus, doing it using redstone mechanics makes it even harder, creating a more entertaining challenge. With that said, I look forward to your votes and comments. I would definitely bring it back.
