But maybe the document doesn't have a title, because it was grabbed
from scanning the book, then OCRing it. So what I will facilitate is
the generation of proper metadata (+ more) from a current PDF lacking
such.

So if the document does have a title, my pdftopdf tool will find it,
and add it to the metadata.

I will contribute pdftopdf to poppler.
