I don't think so. Looking at https://github.com/mozilla/funfactory/blob/master/funfactory/middleware.py and https://github.com/mozilla/funfactory/blob/master/funfactory/urlresolvers.py, it strips out the locale before checking if a path starts with a supported nonlocale, and if it doesn't it adds the locale back in. It should just redirect people to the non-locale version.

I tested this on the Affiliates admin and it worked as expected, but we should definitely test this before pushing to be sure.
