I've done that for the last year on every single score I've produced - 
literally 100s of them - and have never had a problem or an error reported. 
That said, I don't think that's what I have in the file giving this problem. 
I did give the full detail in a previous mail, but a skeleton looks like 
this:

\new Staff = "MainStaff" <<
 \new Voice = "MainVoice" { SomeMusic
   << {
       OtherMusic
     }
     \new Staff = "Ossia" \with {
       \remove "Time_signature_engraver"
       alignAboveContext = #"MainStaff"
       \override StaffSymbol #'staff-space = #(magstep -3) % Sets the staff 
line spacing
       fontSize = #-2
     }
     \new Voice = "Testing" {
       Music
     }
     \new Lyrics \with {
       alignBelowContext = "Ossia"
     }
     \lyricsto "Testing" { Words }
   >>
   MoreMusic
   }
   \new Lyrics \lyricsto "MainVoice" { \OtherWords }
 >>

So I think I've got brackets <<  >> including the simultaneous events, which 
includes the existing music, the new Ossia staff, the Ossia music and the 
Ossia lyrics.  So it appears to be right from what you've suggested, but I 
still can't place the lyrics properly without hundreds of warnings.  There 
was no problem with doing this in 2.12.

OK, thanks. This has moved me forward and I can now move the Ossia up and 
down.  However, using default system-system-spacing means that (I've just 
worked out) the staves of the main music don't move apart at all to 
accommodate the Ossia stave - they only move slightly to accommodate the 
ossia lyrics.  system-system stretchability has no effect on this.  I'm 
getting pretty certain that this is the bug - main staves are not spaced to 
accommodate temporary staves.

If I set system-system-spacing #'basic-distance = #50 then I can move the 
Ossia up and down with, for example

\override VerticalAxisGroup #'nonstaff-relatedstaff-spacing #'basic-distance 
= 30

But I don't want all my music to have large gaps in it just to accommodate 
occasional temporary staves.

See my reply to Carl, thanks.
