I've pushed clarifying reference API docs regarding this trait
separation of positive versus negative status types to
https://dedi4.nedprod.com/static/result-v2/doc_result.html.

I appreciate that this change is controversial. However, I am also
minded that there is no point in Outcome v2 covering the identical
ground as Expected, just less well. Outcome ought to be isomorphic to
Expected, be strong at the areas Expected is weak at and so on.
