I have one (at least) fundamental concern about the approach - let's say I'm building an anti-fraud system that uses AI (through API), and maybe I'm asking AI whether my user [e-mail] is a potential fraudster. By masking this email address I'm sabotaging my own AI prompt - the AI cannot longer reason based on the facts that 1) the email is a free public email 2) the email says 'fraud' right in your face.

Valid point, the proxy has the option to always allow domain names through. You will lose some context always I fear. It should be used sparingly when you need a frontier model but also want to send sensitive data.

You can do those as a sperate prompt.
