Now that you've stumpled upon it, I think I've hit upon the very same
issue in the past with classes in other libraries, and had to work
around in the same ways (adding a getter and/or setter methods).

The path of least resistance was just to change the method name for the
2-arg variant, which I just checked in.  Doing a getter isn't really
straightforward, as we don't actually store the credentials itself. 
Retrieving it from the credentials provider that we do store is also not
straightforward, since it requires the AuthScope, which we also don't
currently otherwise store.  It's not worth messing with.
