I don't know whether it should only be used with the "cups" device or for all of the filtering needs - just do some testing with different media sizes to see what happens... :/

Thank you very much.
For me it seems that this Adobe matching is not actually needed with
CUPS and can be even bad, as Ghostscript probably does not know all
existing page sizes and, in addition, the printer's page sizes are
available in the PPD (static or generated via IPP) and pdftopdf and
often also the printer driver take care of the right sizes by
themselves. So I think that one could put -dNOMEDIAATTRS in all
Ghostscript calls of the CUPS filter chain then.
