Zombie piglin curing

When you can cure zombie villagers, why shouldn't you be able to cure zombiefied piglins? A lot of players (especially superflat players) would like to have this feature, as pigmen bartering is an excellent way to obtain loot. But sometimes you don't find zombie pigmen, but only zombified piglins spawn. When this would be added, you could also use pigmen bartering in the overworld.
