This seems like a footgun, no?  One library adds some listeners, then 
another adds some, then the first removes them all, breaking the second 

Or worse yet you do this on a <select size="1"> and remove the click 
event listener that opens the dropdown...

Or did you not actually mean _all_ listeners?  Perhaps you meant "all 
the listeners that this script (or this function or some other unit of 
related code yet to be defined) has added"?
