Yep. Unfortunately the trap extends further than just the Django admin site itself. ModelForm and generic views are what power the admin site and they're exposed and you're encouraged to use them. Same with the low level crud permissions it creates. Once junior devs start doing the remaining 20% without rewriting you end up with something really difficult to maintain.
It's not just the junior devs. A client once came to me with something that looked like 99.9% is just ModelForm, some CSS, and money. I should've taken 25% upfront and said no to the increasingly absurd change requests, but oh well.
