A labels don't help anyone, they're only interesting for lookup. Real humans need the U labels. If a phone manufacturer really needed to be independent of the version, they could send Unicode to the server and then the server can do the mapping.
IMO the name should only be converted to an A-label for resolution. Normally it should be a Unicode name.
