Please note that this problem (and the "solution" of moving the tie
engraver to the staff context) has been discussed several times before
on the mailing list, including the following threads:

Hm. Maybe ties should work at the staff level as fall-back. Or even
just explicitly. Wouldn't it be nice to be able to say ~~ and have the

have to start guessing the right \voiceOne and similar settings in order

The trouble is that << \\ >> creates new Voice contexts. So not only ties but
everything (spanners etc) does not connect to notes in the outside Voice
context. Even if you have something like:
\relative c' {
c( << { f g } \\ { f, g } >> d')
}
the slur does not notice the notes inside the << \\ >> construct.
The solution is put all related notes together:
\relative c' {
<< { c( f g d) } \\ { s f, g s } >>
}
or avoid << \\ >>, much longer to write:
\relative c' {
\voiceOne
c(
<<
{ f g }
\new Voice { \voiceTwo f, g }
>>
d')
}
But I think that this is properly enough documented.
An artificial voice with invisible notes is pretty solidly pointing to
missing functionality.
Agreed. Even when explicitly instantiating voices it remains necessary to use
them for e.g. cross-voice ties. Easy cross-voice ties would be very nice, as
they occor very often in keyboard music. This is an example that works:
\layout {
\context {
\Staff
\consists "Tie_engraver"
}
\context {
\Voice
\remove "Tie_engraver"
}
}
\new Staff \relative c' <<
{ c4 e~ g b }
\\
{ a,2 e' }
But I don't know how it would affect more complex stuff such as multiple
voices with tied chords in a staff.
