Photoshop :: New CMYK Conversion Behaviour In CS4 ?

With previous versions of Photoshop, when an RGB image in a given RGB colourspace was converted to CMYK by choosing Mode -> CMYK, it would convert to whatever CMYK was set as the Working Space in the Color Settings. With CS4 there's a warning dialogue that appears that makes one wonder if CS4 is behaving differently. It now says:

"You are about to convert to CMYK with no color profile. This may not be what you intend. To choose a profile, use Edit > Concert To Profile".

The resulting CMYK would certainly *have a profile* as it's the default selected in the Color Settings > Working Spaces menu. It's the same as if I had a CMYK file and selected Mode > RGB. This would convert from CMYK to whatever default RGB space is set in the Working Spaces menu. Yet from CMYK to RGB there is no such warning. Why not... the same logic would seem to apply.

I think the warning just confuses to user and makes them think an error's about to occur. A more appropriate warning might be:

"You are about to convert to your default CMYK (Color Settings > Working Spaces). This may not be what you intend. To choose another profile, use Edit > Convert To Profile".
