Maintenance scripts from extensions are special in that they can be run from the CLI without the extension ever being enabled, causing weird issues. We created $this->requireExtension('ExtensionName') for that (it goes in the constructor, and is checked after extensions are loaded). Only a few scripts have been updated to use it though.
