These are definitely not equivalent; there are plenty of cases where a label has handled something differently than the artist intended or wanted. But at least in the cases I’m thinking of, they seem to fall within the scope of these discussions:
Naming of deluxe edition releases - MusicBrainz Picard - MetaBrainz Community Discourse
But we’re pretty far afield from the original post. I might make a new post about it, if I find the time.
