I think any further proposals should _definitely_ explain how to write
the given example

g f e d( 
\repeat { c d) e f ( }
\alternatives {
  { g) a b( a \fake) }
  { \fake( e) d c( d \fake) }
  { \fake( d) c d( e }
}
d c) d c

with them.  According to what you wrote above, this would probably
become

g f e d( 
\repeat { c d) e f ( }
\alternatives {
  { g) a b( a \rightPart) }
  { \leftPart( e) d c( d \rightPart) }
  { \leftPart( d) c d( e }
}
d c) d c

I have no idea what "rightPart" is supposed to mean here and why ( on
its own would _not_ be a left part of anything.  We also have no matchup
of left and right parts: the \rightPart in the first alternative is the
visual match of a paren not called \leftPart, and it connects logically
to the closing paren in the \repeat phrase which is not called any part
either.
