nit: Bleh, not a giant fan about how one is a guest "session", but the other is
a system "profile". Seems inconsistent.

Dy'arg, ok, I'll fix that in another CL. IsGuestSession() -> IsGuestProfile().

+  // Returns whether it is a system profile.

Please document what a system profile means, and when it should be used.
