Till,
The point should not be to propagate hundreds or thousands of printer-specific knobs to trip up the user (even expert users!)
It makes more sense to provide a Gutenprint-specific web UI that allows (expert) users to do test prints and tweak those knobs. Once you are happy with the settings, save them with a name ("Bob's Photo Preset") and expose the presets as single vendor extension attribute, which then shows up in the print dialog.
