Setting this to zero does not shorten the retention period. It removes the trash entirely, so Move to Trash becomes Delete Permanently and there is nothing to restore from.

The constant does not cache anything. It tells WordPress to load one file very early, and if that file is missing or left behind by a removed plugin, the result is a site that either ignores the setting or fails to load at all.

This is the last filter before a template is loaded, and it is one of the few where returning nothing produces a blank white page rather than a default. Whatever the callback returns is loaded, including an empty string.
