triggerHandler vs. trigger in jQuery

Out of curiosity -- what is the purpose of / use cases for jQuery's triggerHandler ? As far as I can tell, the only "real" differences between trigger and triggerHandler is whether or not the native event fires, and event bubbling behavior (though triggerHandler 's bubbling behavior doesn't seem hard to replicate with trigger in a few more lines of code).
