Dagbani is now fully supported in MediaWiki core as all the most used messages have now been translated.
If special configurations for Dagbani in the Wikibase code were made to allow support for lexemes or Wikidata terms: e.g. if dag was added to the special list of languages in which lexemes are allowed, then they should now be removed.
see:
Not used for Lexemes, but added as a monolingual language code. Will remove it there.

@Mbch331 Since you claimed this and removed the patch-welcome tag, are you also going to submit a patch to remove it from wmgExtraLanguageNames? (see the last link in the description)
