-----------------------------------------

LGTM +1

bq.  I don't see any confusion about what "management tools" can be. 

Ambari, obviously. 

I don't actually know if it uses it, but the tag at least marks up for anyone maintaining it in future that this is a management tool API which isn't for broad use, *and which we may break across point releases. Up to the tool teams to track, which, given the nature of the product releases, they should be able to do so.
