The wrapping spliterator (that encapsulates the source spliterator of one element and the explode op) is not very smart. 

We could use the same spliterator from iterator trick to extract some parallelism by further wrapping the wrapping the dumb wrapping spliterator. However, at the moment i am not quite sure of the exact rules when to apply this trick.
