That does not look simpler than

\new Staff \with {
  keepAliveInterfaces = #'(
     rest-interface
     bass-figure-interface
     chord-name-interface
     cluster-beacon-interface
     fret-diagram-interface
     lyric-syllable-interface
     note-head-interface
     tab-note-head-interface
     lyric-interface
     percent-repeat-item-interface
     percent-repeat-interface

     ;; need this, as stanza numbers are items, and appear only once.
     stanza-number-interface
   )
} ...

Thanks a lot David!!!

Here it is a complete example that compiles (just in case others need it).

\version "2.19.82"

rh = { \clef treble 

       a1 b1 c'1 d'1 \break

       a1 b1 c'1 d'1 \break

       a1 b1 c'1 d'1 \break}

lh = { \clef bass 

       r1 r r r 

       a1 a a a

       s1 s s s}

\score 

{ 

  \new PianoStaff <<

    \new Staff \rh

    \new Staff \with {

      keepAliveInterfaces = 

      #'( rest-interface bass-figure-interface chord-name-interface cluster-beacon-interface

          fret-diagram-interface lyric-syllable-interface note-head-interface tab-note-head-interface lyric-interface

          percent-repeat-item-interface percent-repeat-interface stanza-number-interface

          )

    } \lh

  >>

  \layout {

    \context {

      \PianoStaff

      \RemoveEmptyStaves

      \remove "Keep_alive_together_engraver"

      \override VerticalAxisGroup.remove-first = ##t

    }

  }

}
