This has been discussed many times in the past on the forums.
I am strongly opposed to this change.
Again it seems to be down to those that want to use Musicbrainz to help tag their collection versus those that want a database. That has been discussed before.
There are bigger issues there. I am aware that many of you seldom edit releases that have feat. artists but the big issue and only go after the low hanging fruit but the majority of releases I change it is all to do with feat. artist often releases that have every track with multiple feat. artists.
Last time a looked extensively at new content that needed featured artists added to musicbrainz about 70% were wrong. By wrong I mean feat. artist in the title. Featured artist in the artist! e.g. the artist was called “artist a feat. artist b”, etc, etc.
That is the thing to address reducing those numbers down. Prompting when they are entered in this way, etc.
For style there are other larger issues I see at play Anthology/2 in 1 releases, etc.
