I don't consider this a hack. Using parallel spacer rests is a very
common construct. If it seems ugly then you can always move it to a
function to hide it away.


\version "2.16.0"

endHairpin =
#(define-music-function (parser location mus) (ly:music?)
  #{
    <<
      { $mus }
      {
        <>-\tweak #'minimum-length #5 \>
        #(skip-of-length #{\scaleDurations #'(9 . 10) $mus #})
        <>\pp
      }
    >>
  #})

\score
{
  \new Staff
  {
    c'1 \endHairpin c'1
  }
}


This function can be made more general (pass in dynamic, hairpin
length, etc.). However, it does show that you can simplify and hide
these constructs when desired. The syntax is very adequate for this.
