I guess that would depend on your definition of “official”. But, yes… the LIDB is/was supposed to be the gospel. However, there are and have been satellite databases for decades. They are all supposed to communicate and play nice together. But… you know how that goes. Just like, if you had a CNAM provider, you weren’t allowed, by contract, to cache the dipped data. That rarely stopped anyone from doing it.
