I don't think there's much meaningful information to glean from this list. The package at the top is literally just a package.json that installs all the packages published by one particularly prolific npm author, it doesn't have any serious purpose. Many of the other high-ranking packages simply have put their devDependencies in their dependencies, resulting in a bunch of babel plugins and the like (a mistake to be sure, but not indicative of anything in particular about the state of npm package usage).
