In Hibernate ORM 6, SessionFactory now extends AuditReaderFactory. Problem, AuditReaderFactory is located in package org.hibernate.envers.internal... so it's supposedly an internal interface?

• If that interface is actually internal, it should not be extended by SessionFactory
• If that interface is not internal, it should be moved to a different package.

I noticed that while working on Hibernate Search: we have a tool to check that we don't use any of Hibernate ORM's internal APIs, and it started to flag every use of SessionFactory, since it exposes an internal interface.
