Mediator just about creating a stable API. The various mediated objects offer functionality, the mediator makes a common (and stable) interface against that functionality. Consumers only see the mediator and this leaves you free to change the mediated objects out if needed.

So it's the same thing as always: make a stable API and code against it.
