OK, sounds good to me, that would make the feature-implementation even
easier.

using promises that informs the caller about HAR data being ready, so
instead of firing ready a promise would be resolved instead. Something like
as follows:
HAR.triggerExport(options).then(function(result) {
var har = result.data;
console.log(har);
});
Would that work for you?
