I would like to see the ability to make collaborative playlists be invite/ request to join only as I am TIRED of bots adding random Pesukone/ Empty Elevator/ S Productions songs to mine and my SO's Playlist(it's also bad music). It does not matter if I block the account and delete the songs, a new account always comes back and re-adds the same songs. As a premium member I believe you can do better, Spotify.
