we shouldn't go the way of a callback function, we should use Events.

Not necessarily for this function. The function itself could listen for the event when rendering the wonderwall and thus make it a bit easier for integrators. Its basically how wonderwall itself works or the ensureFirstNameLastName. They create a listener (in that case for post message) and then render the component to encapsulate the functionality.

Imo the function being a promise would be the nicer way instead of a callback though. Its basically the same just a little more flexible.
