Agreed.

If the Scheme function took a context [name?] parameter, that would solve any 
problem in this regard.

Mostly, that's already possible now:

\version "2.13.9"
ms = \relative e'' {
   << { \voiceOne e4 e c d } \context Voice = "2" { \voiceTwo g,1 } >> 
\oneVoice  |
   << { \voiceOne e'4 } \context Voice = "2" { \voiceTwo g, } >> \oneVoice e' 
e2   |
   << { \voiceOne e4 g g2  } \context Voice = "2" { \voiceTwo g,2 r } >> 
\oneVoice  |
}
\markup { ORIGINAL: }
\score { \new Staff \ms }
editionATweaks = {
  s1
  \override Voice.NoteHead #'color = #red s1
  \override Voice.NoteHead #'font-size = #4 s1
}
\markup { TWEAKED: }
\score {
  \new Staff <<
    \ms
    \context Voice = "2" \editionATweaks
  >>
}

Agreed: a more surgical approach would be superior.
