Because there is no listener for string numbers, so
Rhythmic_music_iterator retains them as articulations in the music.

Looks like what you actually want is removing the Fingering_engraver so
that Rhythmic_music_iterator retains the fingerings for the sake of the
New_fingering_engraver.

Of course, that means that <c e f>-1-2-3 is going to stop working.  But
it does not sound like you want it anyway.

I do hope that the Fingering_engraver is responsible just for
fingerings.  I distinctly remember the New_fingering_engraver doing
quite a bit more.

And removing the Fingering_engraver indeed does what you want.  And it
does not appear to be listening to anything but fingering events,
either.
