The question was about advantage of RGB<->CMYK, not about printing 
greyscale and control it with RGB curves.

CMYK has one additional channel - black one. It is generated after 
conversion of RGB to CMY from pixels, where are all CMY values > 0 . 
The generation of black chanel is most sensitive part of CMYK 
workflow and "standard" CMYK profiles have black channel generated 
for ofset, not for inkjet. So if you use CMYK data in some kind of 
ofset space, the inkjet RIP or driver must konvert this CMYK to 
CMYK(mck) space for particular inkjet. And:
