You could add this command to your map when you are about to release it and you are sure everything works fine. So you could be 101% sure that your "customers" will not annoyed by that black error box although the map works perfectly but you forgot to remove/change a litte remnant of your 10000 lines of code that actually has no impact on the map's gameplay.
YES, I KNOW: You could just remove -showscripterrors from your Arma-link, but actually nobody who uses that parameter will remove it (since it's a precious tool - for mapmakers).
Edit: This command should also prevent the pop-up-error-dialogues that have to be confirmed by mouse-click. And maybe also the entries to the rpt-file.
