I rejected https://meta.wikimedia.org/wiki/Requests_for_new_languages/Wikibooks_Rajasthani, mainly on technical grounds. First, it was stale—open since 2007, and only two comments (other than inappropriate ones that were reverted) since 2011. (The age of a request is not a reason to reject by itself, but it made this situation just that much worse.) Second, it pointed to two ISO 639–3 codes: both were macrolanguage codes, and the request was pretty unclear as to whether it intended to cover one, the other, or both. So I closed the request, and invited anyone interested to resubmit a more focused request.
