Yes, calling it will actually update the message / progress / title

Right, they can have a more complicated binding such that:

progressIndicator.progressProperty().bind(
    Bindings.when(task.runningProperty()).then(task.progressProperty()).otherwise(-1)
);

Although they can do that with option #1 too.
