That's abstract, but the result is much better. The one remaining
issue is that if the switch to RhythmicStaff occurs on a line break,
TAB is still printed on the first subsequent line. I can live with it,
but is it possible to prevent that? Simple example below. TAB is on
line 2, but not line 3.

\version "2.19.25"

\new Line {
  <<
    \new Devnull {}
    \new TabStaff { \relative c { c1 } }
  >>
  \break
  \new RhythmicStaff { 1 \break 1 }
}

\layout {
  \context {
    \name "Line"
    \type "Engraver_group"
    \consists "Axis_group_engraver"
    \accepts TabStaff
    \accepts RhythmicStaff
  }
  \context {
    \Score
    \accepts "Line"
  }
}
