Agreed, this would be very useful. 

The only (practical) issue I see is that Weld currently doesn't expect AnnotatedTtypes to be respected for EE-style injection (in some/all cases). I suspect that it should (nb. this is large a change in the container integration contract).

I think it should be:

 <ee:Produces />
 <ee:PersistenceContext unitName="customer" />

What was the reason for introducing the special producerField keyword?
