The ONE thing that this protocol brings to the table is the idea of strong consistency in federation. The only issue is, it makes that strong consistency so resource intensive and so hard to implement that it decreases community servers' ability and ease of federation!!!!
And also, NOBODY CARES ABOUT STRONG CONSISTENCY IN SOCIAL NETWORKS!!! Social networks are built on the idea that we all have a different view of things. We care about seeing stuff from our friends, not seeing EVERYTHING.
