That wouldn't really be a good idea. Someone could steal your phone and replace the TouchID hardware. Then this popup comes up and they say, oh yeah this hardware is totally legit! Then they get your data, impersonate you, charge stuff etc.

I think it's totally OK not to accept authentication from an unvalidated device, but a legitimate user should be able to do the validation.
