Correct. All desktop printers want to be told to print RGB data, and
it's the printer's software which makes the RGB=>CMYk conversion. The
printer manufacturers believe they know best, and they probably do ...
and it makes it a lot easier for us too ... not to have to worry about
tweaking individual ink curves and spot density, and whatever else.
In fact if you did need to print to a CMYk device, it would probably
be a professional printer, who would want the RGB file, and need only
know what color space it was in. If you always used a specific
professional printer, you probably should beg him (her?) for a printer
profile, so that you could set up "soft proofing" and knowledgeably
predict where your RGB was going to end up.

"Real World PS" implies "CMYk spaces are based on the behavior of
real physical devices, but the RGB working spaces typically are not."
This would imply RGB working spaces are better adapted to device
independency. RWPS says elsewhere CMYk spaces are "considerably"
smaller than monitor gamuts ... and I believe both of these reasons,
taken together, is why no one has developed a device "independent"
CMYk working space.

Bruce does hang out and is quiet expressive at the Adobe "color
