CLI icons are not necessary for daemons which are autostarted (e.g. OpenSSH server). However they are necessary for applications (or servers) which can only be started by launching X Terminal.

So, if openntpd autostarts, is a daemon, and requires no user intervention to get its benefit then (AIUI):

1. It does not need a CLI icon (or CLI icon badge)
2. The description needs to be clear that the user doesn't have to do anything as it runs in the background.
