So, is there a good reason? Well it will not. JPA needs some identity for the entity, something that you will give to entityManager.find(Class, PK) method. Doing entity without PK is a corner case that everyone solves differently, adding better support for such corner-case may result in dirtier APIs and huge time investment for developers, which can be used better.
