People overwhelmingly use defaults. The default shouldn't be problematic. Since we already ship an us english version among many others THAT version should have this feature disabled or show the actual punycode in the url bar.

I'm honestly unsure how you can possibly make a browser that allows look alike characters secure against phishing but at least its a different sort of trade off when you are talking about populations of users that might actually encounter non phishing sites using these domains.
