This thread was triggered by a request in the german forum
https://lilypondforum.de/index.php/topic,105.msg686.html
While I think there is a working sollution over there, I now try to
explore whether LilyPond could be improved with regard to this topic.

I can fill an empty bookpart with a header using ly:book-set-header!
I can fill an empty bookpart with scores using ly:book-add-score!
But obviously there's no possibility to get a paper into an empty
bookpart. Otherwise the answer would have been dropped hours ago.

What's needed to have/get/code such a function?
