While I agree that it isn't a compiled language in the same sense that you compile it yourself within your IDE, it is my understanding that cold fusion is itself a cf to java compiler (among other things).  So the compile time checking "could" happen, but not in the same why you would see in java.  At first run (compile) time the interface implementation could be checked and an error could be thrown/displayed to the page like any other CF Exception.

I agree this is the overall desired goal of interfaces in CF but if the interface is not enforced it becomes somewhat useless doesn't it?  What good is type checking if the CFC/Object doesn't fit the description of what that type is?

Not for this reason. CF is not a compiled language, and the typechecking that interfaces do happen at compile time. Bit of a catch-22, because the checks you want HAVE to happen at a place that doesn't exist in CF's world.

The real reason for wanting interfaces is for the runtime typechecking that CF does. I.e. declare an interface, specify the interface as an argument type or return type, and then pass CFCs that implement the interface. This is a far more important reason for wanting interfaces in CF, and fortunately, it's one that doesn't require a paradigm shift in CF language processing to implement, so it might actually happen at some point.
