The new alerts are designed to help hub authors keep their games current or address problems that made them unlistable.

Currently we can't make these a one-shot alert anyway due to the way the alert system is structured; I was however able to make them properly update the spinner when they're new. So really the only way to nix the item from your to-do list is to do something about it.

Game helpers also are notified of entries they can manage (which should help users who make their regular key a helper but publish under a production key), only they now have the option of removing themselves as a helper if they don't want to be involved.

Since this isn't actually a feature request, I'm closing it.
