I would have liked to have seen a comment for what this code is doing (why not
put this code up in the constructor instead and avoid registering for things in
the first place)? Putting it here is fragile as someone may register as an
observer for other classes (such as OAuth2TokenService) and won't handle the
case of a managed profile.
