Appears my response got lost somehow. I vote for #3 as it's the most configurable (and affects nothing contrariwise). In addition to believing we use flags too often, I don't think having a flag solves the problem very well. A couple of examples show why: you want a few instances having floating IP(s) while others do not you want multiple floating IPs for an instance
