|Open||None||T144272 new monolingual language code requests for Wikidata (tracking)|
|Resolved||Ladsgroup||T167259 Add monolingual code fkv (Kven Finnish)|
The patch got reverted because it's already there. The monolingual code is there and you can add statements for that (for monolingual texts) but regarding label/description, that's something else and related to mediawiki i18n.
