I don't see answer to my 'is this experimental/will it be marked experimental' question. I ran into some issues trying to use the feature and suggested that a feature likes this needs polish else it'll just rot, unused. Has polish been applied? All ready for another 'user' test? Suggest that you update here going forward for the benefit of those trying to follow along and who are not watching JIRA change fly-by. It looks like doc got a revision -- I have to check -- to take on suggestion made above but again, suggest, that this thread gets updated.
