The Ethnologue link in footnote 7 of the paper has utm_source=chatgpt.com at the end, so I suspect whoever was tasked with listing languages and determining their status thought this wasn't important enough to do it themselves and just had ChatGPT give them a list. FWIW, Ethnologue does say that Ghari is "Stable" https://www.ethnologue.com/language/gri/ Meanwhile Swedish is "Institutional," the highest possible level of vitality https://www.ethnologue.com/language/swe/
