I've never seen it put quite like this, but it feels right and is refreshingly concrete. Trust the abstractions you can actually design/control for, treat all the other ones as suspect. One still needs the wisdom to tell the difference, but at least focusing on "feature request" focuses the mind. This is at least simple even if it is not "easy".

An argument against OOP where you first need to define/explain differences between composition/inheritance, Liskov Sub, compare and contrast with traits, etc is not really that effective when trying to mentor junior folks. If they understood or were interested in such things then they probably wouldn't need such guidance.
