I am polling feed.query to get the authorPHID and objectPHID. Say A commits something for which B is an auditor. It would be useful to get the PHID of B from the the objectPHID of the story. Also, after auditing if B raises a concern or accepts the commit, I want the PHID of A from the story. Right now the authorPHID, committerPHID and pusherPHID are not returned by the diffusion. querycommits.
