Re: [whatwg/dom] [Proposal] Add EventTarget.getEventListeners() (#412)

It is an important security property that nobody without a reference to my listener function can remove my listeners.

If a use case is cloning a node with all listeners, perhaps this could be handled with a "copyListeners" API (taking event names as filters, eg) without the need to expose the listener references directly?

What about adding a new "addEventListener" option that opts the listener in to being unprotected? That way the default would remain the same - secure - but users who wanted to waive a bit of security for the convenience of jQuery-like event manipulation could do so?
