Seems like the case Tim mentions could be handled using acr and auth_time.
So rather than an arc with something like
urn:google-auth-claims?max-age=10&two-factor=true, an acr with
urn:google-auth-claims:two-factor might be used to indicate 2 factor
authn and the auth_time can indicates the session freshness.
Yes, it means looking in two different places. But that seems easier
than looking in one place but having to parse two values out of it.

One of the reasons we implemented our own solution was because it was unclear how to use ACR. Perhaps more examples in the documentation would be helpful. Are you proposing that a domain could have an acr value such as "http://example.com/auth_level/0" ?
