This was prompted by a couple edits I did today, but also based on this ticket.
For many years, we’ve standardised “ft”, “featuring” and similar join phrases into “feat.”. This made a lot of sense when we were placing them all on the title for the time when we could do better (and it’s what powers this very useful report to allow us to migrate them now!). But does it make sense now, when we have proper artist credits and join phrases? We’re already not standardising any others (“con”, “with”, “avec” and the like). So why have a specific exception for “featuring” variants?
I don’t think there’s any reason inside MusicBrainz proper to do this anymore. I can see how having “feat.” only makes it easier for external users like Picard to manipulate the artist entry, but this isn’t ideal already as it is (since it’ll miss the aforementioned versions in other languages) and sounds like it would be fixable by just making the regular expressions a bit more open (@Freso suggested something like
/f(ea)?t(\.|uring)?/ might work).
Is there a good reason not to deprecate the requirement to standardise “featuring” variations to “feat.”?
