That’s a misunderstanding, I didn’t want them to be turned on by 
default. The question is, is there any need for something like this:

\layout {
  \context {
    \Voice
    \CompletionRhythmsOn
  }
}
\score {
  <<
    \new Voice { … }
    \new Voice \with { \CompletionRhythmsOff } { … }
  >>
}

That’s where I’m not sure; I only use the Completion…Engravers for 
ancient music, where it will generally be used in all voices at the same 
time. But there may be different use cases for modern music (e.g. with 
canons, motifs appearing on different measure positions…).

Best, Simon
