> A good grasp of overall architecture allows you to produce your own heuristic for how to navigate the code, where to look for problems, build internal models of where things might be going wrong, etc. This is the benfit of using a framework, if you are building different projects. Learn one architecture intimately, and you save a lot of headroom. You can also hire people familiar with the framework, who have built this intuition already, even though they have never seen your codebase before.
