True.

No, this means it's ignoring whathever CMYK embedded profiles in such placed
images, allowing the CMYK values to pass unharmed in the output stream.
Whether file or printer. It's still not explicit enough to my taste and I
hear they left this unchanged for CS3 :(

Ah! That's a different story. In your case, you may consider changing the
default setting for CMYK and opt for actively managing their color. But do
that after a careful analysis and reasoning. I used to believe that all CMYK
colors needed management, no matter what. But not anymore.

You have to ask yourself what confidence to attribute to the embedded
profiles. Many times, the profile is tagged by Photoshop on the way to the
file but it does not correspond all that accurately to the "intent" of
whomever had that file pass through their hand.

If you do then, to be consistent, it must also be done for output
(converting on Export or Print). It's a two edged question -- damm if you do
and damm if you don't. You will have to be a little bit more specific.
