Yes, PDF files passed to EXTRA_IMAGES will be rasterized.

A possibility, requiring GDAL 3.0, is to use the new approach using a XML composition file :
https://gdal.org/drivers/raster/pdf.html#creation-of-pdf-file-from-a-xml-composition-file-gdal-3-0

With that, you can include a PDF, and its content will be inserted 'as it'.
That said, there is a restriction currently that the dimensions of the inserted PDF must
be identical to the ones of the output PDF.
