But if we accept the premise that "it's acceptable in some cases to have unwrap() in code that targets 'production'" then it wouldn't make sense to have a production profile that bars its use. The word "production" is in the global namespace and I think you want something more specific to your use case.

Rather, one could define a rust coding guide for themselves that deems unwrap() inappropriate for production use. (and in that case use the lint Steve suggests).
