One example where, I believe, consideration of economics is due
Wrt this example: at first, a routing technology should be provided, that gives you all the options - of course, in a scalable way.
For comparison, consider an intradomain-OSPF network topology, and hereby some (destination) node with several links to several neighboring nodes. It can be assumed that at some point in time the rtgwg might provide good solutions to do IP forwarding in compliance with preferencing any particular ingress link at the destination node. Good solutions means, this preferenced choice shall be well balanced wrt to the total traffic to that destination node.
However, with the current inter-domain protocols you can forget the pursuing of such goals.
