John,

The signal would be handled via support for an EPP extension XML namespace in option 2, an operational practice XML namespace in what I would call 2b, or most likely a new contact XML namespace (contact-1.1) in option 1 for RFC 5733.  The XML namespace would be reflected in the EPP greeting services and login services.

    That makes sense, but it also seems needlessly cruel. I expect
    registrars would build ad-hoc lists of who handles EAI and who
    doesn't, to provide better reports to their users, which would
    then inevitably get out of date.

    If we do this it really would be nice if there were a signal for who
    handles EAI and who doesn't.
