[Registering your application](https://stackapps.com/apps/oauth/register) as a Stack Apps [tag:app] is necessary in order to obtain a [higher request quota](https://api.stackexchange.com/docs/throttle), [authentication](https://api.stackexchange.com/docs/authentication) and [write access to the API](https://api.stackexchange.com/docs/write).

What happens if the questions is [closed because of being a placeholder question](https://stackapps.com/a/7591/34061), and when it's deleted (e.g. by [Roomba](https://stackapps.com/help/roomba))? Does the app still qualify for those registration benefits?
