Not saying either way, but something to chew on when it comes to Domain models: https://www.cosmicpython.com/book/chapter_02_repository.html https://www.cosmicpython.com/book/chapter_02_repository.html I love this book and it explicitly addresses a lot of painpoints in designing complex systems. For example, business counterparts might request writing to CSV instead of database. You want to decouple domain models from RDBMS.
