Rich Hickey and Clojure have a low-tech solution for you: use maps. This “wiring through all the layers” problem is basically self-imposed by the use of static typing for data objects. Instead you should mostly pass around maps, validate that the keys you care about are present, and pass along the rest.

Of course your Java peers aren’t going to be happy about this, so in some ways a new language is needed to establish a context for this norm. But the limitation isn’t physical, not even in Java.
