Right. I should have mentioned that immutable leaf nodes are OK to
appear more than once. Like java.lang.String, or the generated type-safe
enums.

With leaf nodes, we can handle all those correctly. Just to remind you,
we already support the type-safe enum pattern.
I believe the case discussed here is using the same JAXB-generated bean
more than once in the object graph.
