How does CUPS know how to do that?  Some sort of meta-PPD mapping that
takes CUPS keywords to the vendor-mangled ones?  The same mechanism
would seem to be usable to take PPD-standard keywords to vendor-mangled
ones, so CUPS could handle %%IncludeFeature: *Duplex DuplexNoTumble
and treat it as if it were %%IncludeFeature: *EFDuplex Whatever.  That
would be CUPS adding value and sanity to the existing state of PPD
document management support, rather than contributing yet another set
of different keywords specific to CUPS.
