MBS-4548 adds artist credit pages, such as https://musicbrainz.org/artist-credit/2329054. Once these are public, it would probably make sense to change the way the Edit Artist Credit page works. It currently depends on the artist it was accessed from and uses that artist's layout (see for example https://musicbrainz.org/artist/935df0f7-26ae-41e4-87dd-d9c6c0253f0f/credit/2329054/edit if editing this artist from the London Promenade Orchestra page). This seems unneeded now that we have an ArtistCreditLayout we can use - it would seem more sensible to just turn all these different artist-based edit links into https://musicbrainz.org/artist-credit/2329054/edit (which could then also be linked as an extra Edit tab from the artist credit page itself).
