CLI Command is just UI detail exactly like HTTP controllers. They are not place for business logic. This problem is already known as https://en.wikipedia.org/wiki/Magic_pushbutton anti-pattern. Thus, it's better to ask sane API (decoupled from UI) from mentioned vendors (Doctrine and others) in order to make things instead of asking abstract CLI commands.
