- UNORDERED: should the returned collector be UNORDERED if either of the provided collectors is UNORDERED? (Current draft says both.) I think both is the right behavior. If you are collecting: teeingAndThen( Collectors.toList(), Collectors.toSet(), Map::entry ) ...then you might want the returned List part of result to respect encounter order regardless of the returned Set part which doesn't. OK, this makes sense. Seems like it should be "both" then.
