This ticket is requesting the ability to create user permissions at the level of individual resources. This is to prevent editing of other resources. I think this is potentially useful but not sure how big a piece of work this could be. There are other workflow options that could be deployed.
We passed this at the last meeting, since I was able to reproduce it while we were talking, but I was unable to do so again. Happily someone else has been able to reproduce, so I recommend passing again, but we should definitely sharply reduce the priority. I suggest either minor or trivial.
