https://musicbrainz.org/relationship/39a08d0e-26e4-44fb-ae19-906f5fe9435d currently includes this:

• If the karaoke track does not correspond to a particular recording of the original song, link it to the earliest version of the original song.

This does not make sense following the implementation of STYLE-2096.  There is no reason to link 2 unrelated MB Recordings when the Recording-Work relationship can indicate the same attribute without inaccuracies.
