Need some help here: Edit #116374443 - MusicBrainz
Where is the guideline that says how MB names an artist who wrote a work? As in the above thread here I’ve always understood this is based on the original release and how the artist is known. “Artist intent”
An editor is trying to replace “Roger Waters” name with his name as written on ISWC - “George Roger Waters”. Only his lawyers and bank manager knows him by that name. 
On the release in question he was, as he always is, “Roger Waters”.
Images from original vinyl and the current CD release.
When the works referred here were written I don’t think ISWC even existed. As I understand it MB always leans on using the artist’s name as seen on the original release. Part of the argument being - this is not ISWC and you can always go over there if you want to know a bank friendly name.
