In 2011 I've put the request [1] on hold, while we were waiting for the native speakers. Native speakers appeared (with >500 pages in Incubator [2]) and I've moved the proposal to the eligible status, as it's a valid language with a valid ISO 639-3 code.
It is possible that they could pass with the approval, as well, but it should be checked.
