Yeah, and for each piece of boilerplate we remove, we add another few layers of abstraction. At the end of this process we are stuck with crap like YAML and JSON (or, heaven forbid, XML) with the business logic being thinly spread out between logic in shell scripts, shell variables (for CD, for example), in YAML and/or JSON and/or XML within the frameworks in use (spring, mybatis, etc), multiple third-party libraries.

There is no one place where you can find the business logic.
