The row meta joined its first three languages with English commas and cut the rest silently, so a truncated list read as complete. It now goes through formatList (Intl.ListFormat) as a conjunction whose LAST item states the cut, from keyCities.list.moreLanguages ("{n} more", landed in R29): "Hindi, Urdu, Bengali, and 2 more" / "Hindi وUrdu وBengali و2 أخرى" / "Hindi、Urdu、Bengali和另外2种". Three or fewer languages show as they are. Not 'unit': in zh it joins names with no separator, and in ar and hi it still adds a conjunction (studio, measured).
