Hiding methods

Suppose I have an interface like:

```
public interface AbstractRemoteable<T> {
    void operationA();
    void operationB();
}
```

And then have a specific implementation like:

```
@Remotable("myservice")
public interface MyClassRemotable extends AbstactRemotetable<MyClass> {
}
```

I want to be able to hide 'operationB'.

Would you consider that a useful enhancement?
