I agree only in that it is performant, but from a purely computational point of view. Even if it is just a rest api, you still need a database/ORM layer, a validation framework, a migrations system, a way to document it, etc. So, from a developers life quality and company economics point of view, django or rails are way, way more performant, but not as cool I agree.
