Router behaviour on empty (null) root

[Infeligo]

When m.route is called for null root, the modules are initialized, but nothing is rendered (without any errors or warnings). I just encountered this when passing non-existent document.body and it took some time to figure out the "root" of the problem (pun intended). This problem may occur in case of a typo or if you use the element before it has been parsed (yes, a newbie's error).

So I was wondering. Is there a case when null root is desired? If no, then shouldn't Mithril warn about such faulty usage?

Can you post a jsfiddle showing a case where an error doesn't occur? It should throw an error in that specific case: https://github.com/lhorie/mithril.js/blob/next/mithril.js#L435
