Notes workflow improvements

Hi all-

At a developer meeting this morning, several of my coworkers expressed interest in using (shared) git notes in our workflow.  I dug back in the mail archive and found a discussion started by Yann [1] and a patch series [2] that would help the notes workflow.

Unfortunately I'm not finding any further reference to the patch series in the mail archive or in Junio's alt-git repo.  Does anyone know the status of this patch series?
