I consider spot colors much more important than CMYK. I also consider CMYK
a special case of spot colors. Spot colors could be implemented using GEGL ops
that take a set of grayscale buffers (plates) as input and provides
RGB soft-proofing
(potentially even animated for gloss/metallic inks). This would leave
the image processing
algorithms dealing with sane or mildly sane color models like gray
scale, RGB, YCbCr or CIE Lab,
while allowing the user direct control over the contents of spot
colors and seeing a preview
of the resulting processing.

If the above is considered CMYK support I would be supportive of it.
CMYK support in the
form of CMYK and CMYKA pixel buffers as a first class citizen (or even
a third grade citizen)
with support in most operations and routines is something I will
continue to oppose.
