If existing specs would be sufficient for Linux, things would very likely 
have already been solved. I think it was much more work on the Ghostscript 
and Poppler cores and pdftoraster filters, than what was brought up 
recently on the CUPS side. We are still in the specification stage.


As an example, why the three qualifiers are not enough, think of a print 
queue with the following ICC profile qualifiers:
RGB.300dpi.plain_paper

Now move the gamma slider somewhere, by accident or what ever reason. Each 
system, which solely relies on the above three qualidiers, will horribly 
fail. A user can print lots of photos with that settings without getting a 
hint from the system that here/his profile is pretty useless.


Users should not be able to mess up the ICC profile settings. That is 
plain usability logic.

If a PPD is stripped down to just three colour related options + a valid 
ICC profile then we arrive in PPD vendor land, which is appart from user 
settings.
