Comment (by mhanmore):

 I'm only one user and not a dev and not associated with the qgis or gdal
 projects.  But to my mind

 1) pdf is a very widely used format for exchange of geospatial
 information, probably the most widely used for sharing outside of full-
 time GIS professionals.  By way of example, drawings for projects
 undergoing public scrutiny (new roads, new buildings etc.) are always
 published as PDF.  I don't think it is a leap to say lot of users are
 likely to receive data as PDF, and

 2) gdal is specifically designed to be a translation layer for geospatial
 data, so inclusion of support for such a widely used format doesn't seem
 like an unusual default setting.

 Given that, including pdf support as standard seems likely to match the
 expectations of a large group of users.

 I note that whilst `+Poppler` alone seems to have resolved the issues I
 had struck in qgis3, looking at the GDAL documentation
 (https://gdal.org/drivers/raster/pdf.html) it looks like full PDF support
 in GDAL requires additional packages `PoDoFo` and `PDFium` so if a change
 is being made to the default configuration then it looks (to a novice like
 me) like they should be added too (or  maybe `+poppler` also pulls them
 in?).
