getting animals to trust you

Hey minecarft! 

during lockdown I have been walking to ponds with ducks and I noticed the ducks seemed like they had everyones trust. I figured this is obviously a result of people feeding them. What I'm trying to say is when you feed an animal enough it will tilt its head when you are in proximity , like a dog when you hold a bone but it can't teleport to you and can despawn. And for certain animals they may walk away because they don't trust you (cows sheep chickens and pigs maybe)  but if you feed them this will change. This feature will also balance the fact that its quite easy to use flint and steel on a animal and will keep Minecraft less lonely when a animal is trusting you basically begging for food.
