Ok, good points that I hadn't considered. However, I would think that many developers will just use Event#remove without considering the need to remove the event listeners, which could lead to memory leaks.
Maybe an Element#destroy method could fill this gap - remove event listeners, remove element from the DOM and then trash it - a destructive method for when the developer says "OK, I'm done with this element..."
