Not really.  I tried horizontal-skyline first, did a grep, corrected to
horizontal-skylines, saw no difference, tried out vertical...

empty-interval is just "short" for (or rather, less likely to typos
than) '(+inf.0 . -inf.0).

empty seems rather generic as a function name.  I'd rather pick
something less likely for collisions.  An any rate:

empty =
#(define-music-function (parser location item) (symbol-list-or-music?)
  #{ \tweak #'vertical-skylines #f \tweak #'extra-spacing-width
     #empty-interval \tweak #'extra-spacing-height #empty-interval
     #item #})

should likely do the trick.  Possibly you want to stomp out the
horizontal-skylines as well: that would seem to make sense in connection
with extra-spacing-width.
