Which bookpart?  There is one PDF per book, but several bookparts per
PDF.  So it does not make sense to put per-PDF values, like the title
metadata is, in bookparts.

So why don't you then make a title for that master \book?  How is
LilyPond to know which bookpart to take the title from?

I don't really see how LilyPond could sensibly behave other than that.
