I have just realised that all editors wouldn't necessarily see AC as easily as us who are using a user CSS to take benefit of artist credit (AC) special mark (MBS-2966).
Here in that edit for instance, not seeing any differences between an artist with plain name and an artist credit (David Abel), caused some confusion, mixing up two artists with different roles.
But seeing the AC mark, made it obvious to me that there was something special to check out, that it was not a plain normal David Abel.

My display (big dashed underline) is a display that, unlike discogs' star), does not add a character that would otherwise hinder the copy/paste operations. I haven't thought yet of a display/mark that would blend nicely in MB's GUI style.

span.name-variation { border-bottom: 2px dashed maroon; }
