Yes, that works, I am just unhappy by the need to write wrappers/utility code instead of using JPA interface as intended. A few more thoughts

@AllowUnwrap
@Inject
private EntityManager em

however, doing it at injection point is probably the wrong place, so how about at producer:

@AllowUnwrap
@Produces
@RequestScoped
public EntityManager getEntityManager(){}

As a bonus, weld behaviour could be codified in the spec and this would allow a developer override. No other code changes needed when using JPA or similar use cases.

I'm sure it is a bit more complicated that that and I also understand this is a rather narrow use case to merit an introduction of a new annotation/funcitonality in CDI. It seems cleaner and doable though. It would probably make more sense to start this discussion at the spec level.

Feel free to close the issue as needed.
