One of the options is to traverse all music expressions recursively,
and set the music property #'quoted-events to '() if it is defined

untested code: 

killCues =
#(def-music-function
  (location music) (ly:music?)
  (music-map (lambda (mus)

(set! (ly:music-property mus 'quoted-events '())
(set! (ly:music-property mus 'quoted-context-id '())
(set! (ly:music-property mus 'quoted-context-type '())


)) music))
