hyperref: `DocumentMetadata` ignore `pdfusetitle` option #64

\DocumentMetadata{pdfstandard=A-2b}

There is not pdftitle nor pdfauthor in genreated pdf. If we remove DocumentMetadata, it works.

It seems custom driver doesn't set pdftitle and pdfauthor like other driver call \Hy@UseMaketitleInfos.

Package hyperref Info: Driver (custom): hgeneric-testphase.

This is a documented issue/feature. pdfauthor and pdftitle need to be set explicitly in \hypersetup. See hyperref-doc.pdf section 5:

Be aware that some of the options do nothing or have changed behaviour if the new pdfmanagement and so the new generic hyperref driver is used.

and hyperref-generic.pdf section 3:

...the driver will • Not try deduce author and title from documents. They have to be set in \hypersetup with pdfauthor and pdftitle.

Sorry I missed or forgot that issue. As @jpcirrus wrote, it is by design. The generic driver avoids to patch the \title command. Instead we plan to redefine the \title command in the kernel so that the PDF management can set the pdftitle with and without hyperref. This will probably happen with the next LaTeX release.
