JsInterop funcional interfaces question

Hi all,

Why is it necessary to mark up functional interfaces in GWT2.8 with  @JsFunction. Is the standard @FunctionalInterface not enough?

My concern is that pretty soon every new GWT project (which most likely will need some forms of callbacks) would be inflicting on users code like the one below: 

/**

* I wish I did not have to do this to you, but since GWT provides nothing standard and you can not use Java 8 @FunctionalInterface ...

*/

public interface MyProjectNeedsThisAlthoughThisIsVeryCommonStuff_Sorry {

    

    @FunctionalInterface

    @JsFunction

    interface Func {//callback takes no argument

        void call();

    }

    @FunctionalInterface

    @JsFunction

    interface Func1<A> {//callback that takes 1 argument

        void call(A param1);

        

    }

}
