Thanks again. It's nice to have my conclusions verified.

It probably shouldn't be up to the printer driver to determine
this though. Ideally the print driver should allow printing
the largest gamut possible within practical limits, and leave
it up to the profile to do the rest.

If Gutenprint is applying some sort of total ink limit for a
CMYK mode, then this should really be disabled for profiling
purposes, and the ink limit asserted in the profile creation.
