Persona tries to support the notion of one address == one identity, so the only information you transmit to a site when logging in is "my email address is [email protected], and here's the proof."

To help people manage identities, the Persona UI does allow you to pre-load a bunch of your addresses, but the connections there are never revealed to outside parties. In the future, that information will be managed completely locally in your browser if it has native support for Persona.
