Comment #13 on issue 1555 by percival.music.ca: Multiple warnings  
concerning staff-affinities
http://code.google.com/p/lilypond/issues/detail?id=1555

I'm confused, so could somebody clarify:

1. if
  \new Lyrics \with { \override VerticalAxisGroup #'staff-affinity = ##f }
is required to get good spacing and/or no warnings, do we have a very good  
reason why this isn't the default?

2. assuming that we have such a very good reason, is it possible to  
automatically detect cases in which ##f would be better?  Like "if a Lyrics  
context is attached to a Chord context, lilypond automatically sets  
#'staff-affinity = ##t for the Lyrics" ?


I'm not entirely comfortable saying "it's a mistake to write your lyrics  
without setting \override blah #'staff-blaf == ##t".  I'm not saying that I  
wouldn't accept that answer if people assure me that it's impossible to  
have sensible defaults and/or more intelligent code... but I'd like such  
assurances.
