It would be nice to include more debug annotations within LilyPond.  If 
I am not mistaken, we currently have the following options:

  \paper { annotate-spacing = ##t }
  #(ly:set-option 'debug-skylines)
  \override [Non]PaperColumn.stencil = #ly:paper-column::print

For the future, we could add support for these cases:

- Plotting curve control points.
- Visualizing the extents and origins of grob stencils.
- Indicating the relationships between grobs (i.e. parents, children, 
siblings).

Are there other annotations that folks would find helpful?  Providing 
there is enough interest in such support, we should open a ticket for 
tracking the work.
