That seems like a good list, except for the last one. That's OK, too, but I was just now thinking that kind of thing should be decomposed into 2 steps: forming a new server-group from a set of servers, and then applying any change to that new server group. So the deployment becomes one type of change. All the servers that form a new server group would need to be consistent. They wouldn't need to come from the same server-group (although we could require that to make life easier) but their configurations would need to be consistent.
