JQuery :: Binding And Triggering Events On Non-DOM Objects?

I've noticed I can bind and trigger events on objects that are not DOM elements. However this appears to be an undocumented feature, as the docs explicitly refer to the "DOM element" when discussing things like event.currentTarget. Is it safe to depend on code like the example below working in future jQuery releases?

var thing = $({hello: "world"});
thing.bind('bounce', function(e) {
alert('Boing! '+e.currentTarget.hello);
});
thing.trigger('bounce');
