> Note the "failure" bit. The split shard couldn't add a replica. But when you
> use the request status API, it returns a "completed" status.
> Apparently, completed doesn't mean it was successful! In any case, it is very
> misleading and makes it very hard to properly use the Collection APIs. We
> need more investigation to figure out what other Collection APIs might be
> affected.
