I think if i was to implement this it'd be purely for marketing/styling purposes, and making sure to register the plaintext equivalent aswell and setup redirects for everything. That way i could for example display the canonical domain in blackletter but also keep it accessible to users, which would make for a pretty neat effect if it suits the brand in question.
