I could continue to use Native Eclipselink queries to make use of support for hierarchical queries, however I was wondering whether there are any plans to support hierarchical querying in JPA.

Meanwhile, without support for hierarchical queries, what is the 'best practice' for implementing hierarchical querying in JPA?

Hierarchical queries were added to JPQL in EclipseLink 2.5,

see,

Also, you can always use an EclipseLink ReadAllQuery with JPA using JpaEntityManager.createQuery(DatabaseQuery).
