Indeed, there's no reason in principle why Core Data could not be EOF.
Yet a core principle of Core Data is its abstraction of the model
away from the structure of the various persistent store formats.
Core Data already offers the ability for developers to use an
arbitrary schema for a persistent store: You can subclass
NSAtomicStore and use it to implement any schema you like for your
persistent stores, with the constraint that you will get atomic load/
save semantics instead of transactional load/save semantics.
This does not in itself let you use an arbitrary database schema with
an SQLite persistent store. But it does demonstrate that doing so
would not be an abandonment of any principles that you seem to have
inferred.
