Such arrangements don't fully exploit the possibilities of light inks.
Combinations of light inks and other colors do actually extend
the gamut of a device. For an illustration of this, take a look
at <http://web.aanet.com.au/gwg/test8.wrl> with a VRML capable browser.
This is a gamut surface of a Roland 8 color (CMYKOGcm) printer.

In practice light inks will probably go away though, as dots
get smaller. The R800/R1800 seem to be the start of this trend.
