That's why there were separate categories for it, but you deleted them. I would compare it more to Old Church Slavonic in Glagolitic. It was never as common as Cyrillic (except in Croatia) and most textbooks on OCS consider only the Cyrillic variety. But we still consider them one language.

All but one of the categories I deleted were empty, AFAICR. In any case, there's so little of it, and so little is likely ever to arrive, that I guess I'll just pretend it doesn't exist, unless you have a better solution.
