A decade ago exiftool was unable to add metadata to files created by pdfunite. There was no this issue if files were merged by gs.
gs -dSAFER -dQUIET -dNOPAUSE -sDEVICE=pdfwrite \
-sOutputFile=out.pdf in*.pdf -c quit
I have no idea if a better strategy to combine files has been
implemented in poppler-utils since that time.
