No, this does not bring full color management to the process, it brings full 
grayscale managment to the process. If you poke out one eye, and say you still 
have "full visual management" with the other, you are ignoring binocular 
effects. If you build a profile that strips all color data out of the process, and 
say its fully color managed, I feel that makes the same mistake. Its fully 
gray managed. If you want it color managed, then you need a color profile. 

The difference shows up in the flexibility of color profiles: they can print 
and preview many tints and crosstones with the same profile, instead of one 
fixed output. They can cross match similar tints and crosstones on multiple 
devices, and show all available and unavailable tints live in realtime for those 
who want to experiment with tinting. There are advantages and disadvantages to 
both routes, but its important that people realize the difference. Gray 
profiles, as you define them, are two dimensional.   Color profiles (even ones 
designed for gray systems) are three dimensional.
