Nice idea! For multi-system cropped output this is a good temporary
workaround IMHO.

I hope that some of the more powerful LilyPond developers find time
and interest to fix this in the not too distant future.
You might help us with submitting a bug report, BTW – it seems that
the problem has been discussed on the mailing list(s) but I can't find
something related in lilypond's issue database.
