At https://musicbrainz.org/edit/62080159 a surname is being added as an alias.
My intuitive response that this was not a great edit.
Further consideration has me thinking that in some cultures the use of surnames as primary identifiers is common. And in other cultures the use of first names as primary identifiers is common.
So maybe having surnames as aliases in some Locales for some Artists does make sense.
What do you think of the whole thing?
