Well, this is not a cronjob that failed, it's just waiting for input.
Let's say that I did test the cronjob but that it starts "failing" after an update to the tool. My fault, I know, but at least I get mail when it fails while I won't if it's just waiting for input.
This scenario would only happen if a flag became required. Prompting or not it would still be an issue. (And it wouldn't prompt as this is a non-tty environment)
Yes, but in one case the issue would result in a mail because the cron job failed, and in the other case the issue would just cause the the process to hang indefinitely without notice
