Thanks Robert for the feedback. The challenge is that technically, the param keys are part of the method signature. In Objective-C, this is called a selector and you can define multiple methods taking different "keyword arguments" and therefore somewhat overloading the method. This is a very common approach in Cocoa for instance.
So to implement what you are suggesting we would have to do some voodoo to lookup methods which might have a similar selector. That said, I think it's a fair feedback and it's great to hear some of the issues new users are facing.
