Good. Thanks.

When I was trying to update
http://tools.ietf.org/id/draft-sakimura-oidc-extension-nonweb-00.txt , it
just came to my mind. This non-web extension utilizes the sub from the
userinfo endpoint and if there were no assurance that sub in ID Token and
sub from userinfo response would be the same, it would break.
