It probably depends on how far you try to get from angular in angular-based project. As soon as you try to do something differently - it might bite you and bite you badly. As for promises - try to define custom parser or formatter on ngModelController using anything asynchronous :) And yes, you are right - it might be easy to understand other's angular code for you, but when javascript developer come into angular project, try to explain why utility library called 'Service' and why DI does not take care of loading these dependencies :)
