Comment 4 for bug 1567970

I've done some digging in the Routes package <http://routes.readthedocs.org/en/latest/index.html> to see what would need to happen to address this, and it is challenging.

Routes itself can do conditionals: it will match on limited methods. However, as far as I can tell, when there is no match it simply returns None, no evidence that some other method would match.

May not be worth fixing in this iteration of Nova. :(
