On the contrary, I know exactly what I am talking about. The point of attachment to the topology is topology information. Sounding alarms when apps fail due to being passed incomplete topology information is nothing more than claiming the sky is falling. Jim's example scenario was about passing LL's as literals to an app. LL's are topology information about the current point of attachment. The complaint was that the app would fail if it was not passed complete topology information, by specifing which link the target was connected to. Your favorite examples are about multi-party referrals of topology attachment points. Since we agree that the apps don't and shouldn't have complete topology information, we also agree apps will fail when there is an inconsistency in reachability for any topology attachment points passed as literal values. Yet you continue to insist that passing around incomplete topology information is not only valid, it is an inherent right of all application programmers for all time. It is fine for you to have that view. It is not fine when you use that view to prevent someone else from having a different view about how apps should deal with the topological reality of inconsistency. The network is not a flat, ubiquitous, consistent environment, so passing around points of attachment to the topology is a failing mode of operation. Insisting that we optimize for the fantasy scenario of flat and consistent ubiquity, is not helping us deliver useful technologies.
