[swift] Changing the name of an existing policy (in particular Policy-0)

Hi, We are looking at introducing extra policies to a Swift cluster that was built essentially policy unaware (Swift 2.3). So currently all our containers live in policy id 0 (with name of 'Policy-0'). We would like to rename this so that the likes of 'swift stat' give a more human readable name to this policy (e.g 'Default' or 'All-Regions'). Doing some experimentation it looks like this is safe - but I'm asking here to check that I have not missed anything that would nuke the cluster.... Note we are *not* wanting to meddle with the policy id number. regards Mark
