Hi Carl,

actually, whilst it does pass make check, it breaks... all of my own
scores!

I use the following function:

filterDirections=
#(define-music-function (parser location music) (ly:music?)
  (music-filter
    (lambda (x)
      (not (null? (ly:music-property x 'direction))))
    music))

that allows me to discriminate dynamics that have an explicit direction
(even a neutral one) from those who don't.

Of course, I can fix my own code accordingly. But it shows that this
change may not be entirely harmless for everybody.

Cheers,
Valentin
