… if you want to simulate your new protocol to convince everyone how great it is, it is a good idea to do it on a topology that is representative of the real network.
The Power Law paper is actually a landmark — before it, people used random graphs or particularly transit graphs — but the Power Law paper showed you need some nodes with lots of connections and a lot of nodes with few connections if you want a realistic router level topology.
The second paper showed that while Power Laws are cool, they aren’t enough — you need to consider structural/engineering properties as well.
A lot of this looks obvious, but it really isn’t: smart people made mistakes again and again.
