The latter allows developers to migrate their projects to Kotlin without having to rewrite the entire codebase. Such migrations is one of the reasons why we might have to work with JPA in Kotlin. Picking JPA for a fresh Kotlin application also makes sense, as it is a mature technology familiar to the developers.
