Yeah, a fallback has the risk of being a bit surprising in a bad way.

What surprised me was that even though I set form/widget templates of my own I 
still got an error on a json request until I added a form.json.twig and 
widget.json.twig template into the TwigBundle Resource dir:
twig.config:
    auto_reload: true
    form:
        resources: ['FooBundle::widgets.twig', 'FooBundle::form.twig']
