Cure-able piglins

I believe that you should be able to cure zombie piglins, but not for a reason you might expect. The point of this feature is to be able to get a piglin in a skyblock. This would revolutionise the skyblock community, making it possible to start a skyblock, with only a tree. The piglings trade obsidian and gravel, which makes creatinga nether portal possible. The feature be implemented by giving cured piglins the ability to stay in the overworld without turning back into zombie piglins. To cure them you would need to weaken them, and then give them a golden carrot as they are pigs.
