Why is criteria query deprecated in Hibernate 5?

by

We are deprecating the Criteria API in lieu of JPA extension support.

Consider this:

CriteriaBuilder cb = entityManager.getCriteriaBuilder();
HibernateCriteria hc = cb.unwrap( HibernateCriteria.class );
...
query.where( hc.someAwesomeThing( ... ) );
List<SomeEntity> entities = entityManager.createQuery( query ).getResultList();

Contrary to comments, we do intend to continue to deliver Hibernate-specific features, but we want to introduce those through the standard API instead rather than trying to manage keeping two very different APIs that are meant to be complementary in sync.
