Changes between Initial Version and Version 1 of Ticket #52448, comment 2

initial	v1
1		Core _could_ check for the existence of an action on the `wp_scheduled_delete` hook before scheduling the event, we'd need to confirm that the default ~~hook~~ is always added before the event is scheduled, and that plugins can remove the action before the event is scheduled.

3	3	The reason WP Crontrol warns about events with no action is because it helps guard against typos, actions that have unexpectedly gone missing, etc. It's not really a problem to have a cron event with no action, it's just useless.
