A metric that I would like to focus in is dependency depth. We had this with the OSI model way back, but at this point it seems that anything beyond layer 7 just gets bucketed into 8+. We need to know if a dependency is level 1 or level 2 or level 3 or 45. And we need to know what the deepest dependency on our project is. I might be naive, but I think we should strive to reduce the depth of the dependency graph and maybe aim for like 4 or 5 layers deep for a web app, tops.
