Use mopidy-youtube to play playlists etc from other services

Would anybody be interested in a backend that uses mopidy-youtube to play playlists that are available on other services? Like spotify, tidal or apple music? Or even non-streaming sites, like allmusic or pitchfork? Or radio station playlists (eg from or stations using the Australian Music Radio Airplay Project (AMRAP))?
