Rabbit Spawn/Despawn behaviour

Rabbits are a rather boring addition since they add virtually nothing new to the game save for looks and a potion ingredient. Probably not the first time you read this.
Anyways I have a suggestion:
Make rabbits spawn in a more hostile-mob like manner. More regular spawns, not persistent unless fed, maybe even scared of the player like ocelots.
This would introduce a hunting animal you could use as a food source without worrying about driving it extinct in your region.
I apologize for probably misusing this board, since this isn't a bug.
I would still love to hear feedback.
That is all.
