nit since you're just using the existing names in this change: Do "fully
authenticated" and "partially authenticated" have have well-known present/fresh
vs. present meanings when talking about OAuth2 tokens?  If not, names like
HasFreshAuthToken() and HasAuthToken() would probably be more descriptive.  I'm
also a bit concerned that people may think that IsPartiallyAuthenticated()
implies !IsFullyAuthenticated().

That's a good suggestion. I'll create a patch to rename these methods.
