old Zombie villagers

The zombie villagers have had at least three different changes to them throughout the years. First, they all looked like Steve with a big nose and a green villager head, second, they each had a special look for each villager and when you cured them they went back to the job they had before, and last they were changed to all look the same based on there biome. I liked the second one the best because and you could tell the difference between the zombies and know which one you are curing. I would like Minecraft to change it back to the second one, what about you? My gamer tag is ThankedString14 and I play on a console.
