I don't think people think like this enough: which is why you will get bespoke double entry accounting code mixed up with all the other business logic in almost every application that needs it.
The idea of making an abstract double entry accounting module that is extensible it's own thing is rare. It's probably Conway's law at play. There is no one responsible for doing so, the teams were set up with their goals and everyone shares that code.
