We have the second request for the Wikipedia in Dalmatian [1]. Unlike the first one [2], this is factually valid, as it's about the request for a Romance language edition, not a Slavic language edition.
However, it's about a dead language. They say there are ~20 people speaking Dalmatian, but the educational value of Wikipedia edition in Dalmatian is zero. Unlike with a few languages of the Baltic (Baltic and Uralic), where possibility for a legitimate revival is possible inside of the population which ancestors have spoken the language, I see this at this point of time as pure hobbyist work.
If they create a valid pool of native speakers (a couple of them, at least), they could come again and request Wikipedia in their language again.
