https://musicbrainz.org/relationships/artist-label doesn't currently have an appropriate relationship to link common roles seen in booklets ("products coordination", "promotion", "sales promotion", etc.) to labels (since https://musicbrainz.org/relationship/e74a40e7-0f27-4e05-bdbd-eb10f5309472 isn't selectable).

The guidelines should otherwise be the same as https://musicbrainz.org/relationship/46981330-d73c-4ba5-845f-47f467072cf8 (the booklet should explicitly associate the person with the company - it shouldn't be inferred.)
