In my opinion, -b/--bigpdf should be simple to use for
lilypond-book-like applications.  lilypond-book should likely call
lilypond using options leading to good results by default.  For
generating our own documentation, I find 3-4GB of disk space excessive:
using special additional options might be suitable if that helps.  If
the additional options work at least as well under all conceivable
circumstances, they should likely be the default.

-dxxx are options appealing more to specialists (well, there are things
like -dpreview not particularly specialist, but when in doubt, people
are more likely to see/consider "normal" options).

I'm not into the whole font mess enough to make a really qualified
suggestion here.
