The issue I've seen with backbone apps, even written by "good programmers", is that no two are alike. So, when you come into a new app, a nontrivial amount of time is spent figuring out how the original programmers are using it, which libraries they pulled in for stuff like model validations, etc. To be fair, that's somewhat due to the fact that I mostly encounter them in consulting arrangements, and I don't know that any of the other frameworks are much better in this respect. I think I've just gotten spoiled by doing most of my work in Rails, a mature opinionated framework.
