The use-case that I've heard in similar situations goes something like this:

Code makes a request and at some point later hands the request to some
other piece of code which is interested in the result.
The other piece of code doesn't necessarily know if a result has been
returned yet or not. Using readyState it can either simply get
.result, or it can add a event listener for the "success" event and
wait for the event to fire.

I think that makes sense here too.
