I suggest only trustworthy/*:latest images be checked for freshness.
Indeed, when one pulls fresh trustworthy images, some previous versions may be usefully kept (e.g. because they're used by a running container or for any reason one should want to keep a previous version for reference).
Also, I suggest the sleep time be reduced, 2 seconds are long enough to read the message and acknowledge it.
