I agree with that, I think it seems better to *not* use null to signal natural 
order. But even if we did that here, the stream classes like `SortedOps` still 
need to handle null or `Comparator.naturalOrder()`, since the null signaling 
natural order is part of the contract of SortedSet, Spliterator, etc.
