Even there, will Gutenprint get settings from a particular file, or
from the PPD file?

And why would skeletons be different for each printer?

The "recipe file" shouldn't be Gutenprint-specific -- it needs to be
expressive enough for Gutenprint (in particular, either be able to
present curves to the driver or get them applied at some earlier
point).  There would need to be an installation tool, but wouldn't
that manipulate the PPD file?
