That helps in the case where all the rests are staff-wide.

I'll guess an example says more than words:

\version "2.9.19"

\score {

  \context Staff {
    <<
      s4-\markup{LilyPond default, rests in two voices.}
      \relative c'' { c4 d e r | r2  e4 g | R1 } \\
      \relative c'' { c4 b a r | r a g2   | R1 }
    >>   
    \bar "||"
    \break
    <<
      s4-\markup{Reverting rest direction}
      \relative c'' { \revert Rest #'direction
                      c4 d e r | r2  e4 g | R1 }
      \\
      \relative c'' { \revert Rest #'direction
                      c4 b a r | r a g2   | R1 }
    >>
    \bar "||"
    \break
    <<
      s4-\markup{Typographical convention}
      \relative c'' { \voiceOne c4 d e \oneVoice r |
                      \voiceOne r2 e4 g |
                      \oneVoice R1 }
      \\
      \relative c'' { \voiceTwo c4 b a \oneVoice r |
                      \voiceTwo r a g2 |
                      \oneVoice R1 }
    >>
  }
  \layout {}
 }


The warning messages I get from 2.9.21 look like this:

rest-combine-2.9.21.ly:9:33: warning: Two simultaneous rest events,
junking this one
      \relative c'' { c4 b a r | 
                                 r a g2   | R1 }
rest-combine-2.9.21.ly:8:33: warning: Previous rest event here
      \relative c'' { c4 d e r | 
                                 r2  e4 g | R1 } \\

...and "junking this one" is incorrect in the above case.  (Which is the bug
here.  Combining rests in a staff would be a nice feature and would comply
with typographical convention at least for choral music, but that would be
a feature enhancement.)

Cheers,
