I've yet to hear of an actual reason to do so, people keep saying it
seems useful...

Yes, but they're all using it to attach events to every one of the
class, which is why you have to look at use cases, the reason they're
doing it is not because getElementsByClassName is missing, but because
addEventListenerToClass or -moz-binding etc. are missing.
It's the classic mistake of looking at making the workarounds easier,
when you should be looking at making the underlying use easier.
