Excerpt from change request document:

Omati is the name of a village, and not the name of a language, so the name Omati should be replaced by the two new names: Mouwase and Barikewa. Although reports indicate that there is some mutual intelligibility between speakers of the Mouwase and Barikewa languages, speakers of these languages see themselves as having distinct linguistic identities. They recognize that both languages are part of the "Kaser" subgroup, but still identify Mouwase and Barikewa as separate varieties. Lexicostatistics confirms their status as separate languages, as there is only 38% lexical similarity between them.
