Usage example: I was going to add entry for both of them in wikidata item Q1 but get rejected.
Note that according to https://www.wikidata.org/wiki/Help:Monolingual_text_languages , although the policy was not finished yet, it was stated that a language code does not have to fulfill requirement of the language proposal policy for new wikis, and in general a code would be acceptable as long as the language code is valid.
By the way the application form for new monolingual code on this template is greatly different from the form on wikidata. Which of these fields are actually needed?
