Okay, it appears to be a miscommunication of terminology here. What I meant
is DOM APIs in your definition. As Adam said, API fashions come and go. We
should be making new DOM APIs consistent with existing DOM APIs.

I personally find "named arguments" in various library functions annoying
especially when there are only few arguments. e.g.
parent.appendChild({child: node}); would be silly.
