Simply because the index is not a property or attribute of the item.
What you're suggesting is that if I want to map List<MyItem> and
retain the order of the elements, I introduce a new "index" field in
the MyItem and the @OrderBy this field. This will introduce a
tremendous overhead and data integrity issues. Just think of what
you'll need to do to set and maintain correct indexes within MyItems.
Or what happens with many-to-many associations and so on.
Bye.
