Using the configuration option $wgexLingoUseNamespaces[NS_FILE] = false; does not disable Lingo in file descriptions.
The config does work for other namespaces, and adding __NOGLOSSARY__ to the file description successfully disables Lingo. Is there some other setting that I need to use to disable Lingo across all file descriptions?
MW 1.42.1
