Also when restoring from page cache there isn't any response form the server nor data received and we call those delegates to notify the API layer about it. So, if we do call the delegates why not being consistent? It doesn't make much sense to me that the load is committed but there's no main resource loading at all. Ideally, from the API layer point of view, restoring from the cache should be transparent, like it is when loading from the disk cache, for example.
