I'll give you my complaint with Spring: It tries to hide the libraries underneath and offer the "Spring way". But it's always a leaky abstraction, so you end up having to learn both (for example) Hibernate and how Spring interacts with Hibernate. Instead of avoiding a learning curve it just adds a second one. I greet your suggestion to add another layer of abstraction on top with great skepticism.
