And besides, the method write_to_completion_cache(self, cache_type, val) is not used, so for any cache_type object, there is no any UUIDs or human-friendly IDs, for bash autocompletion, it will show nothing.
In a word, completion_cache for bash autocompletion does not take any effect, beacuse there is nothing in cache.
