[REQUEST] CraftBukkit Event EntityBubbleEvent

I am requesting a craftbukkit event thrown when an EntityLiving creates Bubbles while underwater. Why? I'm actually a Plugin-Dev, I just make private plugins. I am requesting this because I have a magic plugin with a breathing underwater spell. I think it would look better if you can cancel the bubble generation while underwater. It makes the players feel as if they are actually breathing underwater. I know of a few breathing underwater plugins that would also benefit from this.
