So these images should illustrate how the spacing is disrupted by trying to
access the stencil for a cross-staff glissando.

This seems like a bug to me.

I applied your override to a similar grob, VoiceFollower, to see if the problem is just with Glissando.  I get the same disruption of vertical spacing.

 \version "2.17.95"

#(define (stencil-test grob)

  (let* ((stencil (ly:grob-property grob 'stencil)))

    grob))

\new PianoStaff <<

  \new Staff = "one" {

    \override VoiceFollower.after-line-breaking = #stencil-test

    \showStaffSwitch

    c'1

    \change Staff = "two"

    b2 a

}

  \new Staff = "two" {

    \clef bass

    s1*2

  }
