SQLAlchemy does. I get that DjangoORM is more convenient and might be good enough. But powerful seems like wrong adjective.

Powerful in terms of productivity. The occasional N+1 query problem here and there isn't a big issue for many projects and means you can launch 10x faster than someone using some other technologies. If you're successful, you can easily write raw SQL and optimize as needed.

DjangoORM isn’t perfect but its power comes from the fact it is heavily integrated with Django (the framework).

Ah, sorry. It wasn't clear that SQLA meant SQLAlchemy in your first comment.
