While I agree with what you say, the dependency tree becomes more complex, I’ve found the alternative much, much worse. You can also “mimic” the old behavior by just forcing all the libraries to compile against a specific version of a library, thereby simplifying your dependency free again. In other words, Nix’ approach gives you the choice, while the current approach forces you into a certain direction.
