That's good.

Some other solutions might not work that way, so clarifying this 
point they way we just did is probably a Good Thing.

I was also thinking about CMYKOG, and I may have been a little 
glib in my dismissal of it.  CMYKOG is essentially a special type 
of 6-color, which is not patent-encumbered, to the best of my 
knowledge.  There's certainly no reason why the user can't have 
Hexachrome(R) if they install proper add-ons, but it couldn't 
ship with GIMP as long as it has a libre license.

After all, there's a way to get PMS to work with Scribus (and I 
believe you can use this to get approximations in GIMP as well):
