@jddarcy Seems reasonable! Chasing down the super-implementation, [Set::spliterator()](https://docs.oracle.com/en/java/javase/25/docs/api/java.base/java/util/Set.html#spliterator()) states that overloads should report their characteristics (even if the documentation linked does seem to unnecessarily convolutedly state which characteristics the default implementation provides). I can open up a new Issue and handle the CSR-bits if @kilink doesn't mind?
