That's exactly the point.

If you don't change anything, you break anything.

The more you _can_ change _without_ breaking other code is proper 
encapsulation, and with this DIP the amount of things that you 
_can't_ change is just increasing. Named arguments _enlarge_ the 
amount of code that you are exposing and that you _can't_ change 
without breaking someone else code.
