I think the problem with not being opinionated is that 3rd party libraries have nothing they can rely on. Do you write 3 sets of templates for the 3 most popular templating libraries? Do you provide models for SQLAlchemy AND Django? Or do you pick your combination of dependencies, and let someone else reimplement your library with a different combination? That's where I think Django shines. It might not have the best templating library, ORM, or routes frameworks. But app developers and library developers know exactly what they have to integrate with. This encourages a better ecosystem.
