Anyway - Illustrator does not claim to be a PDF editor, it only happens

It can use PDF as it's file format, but unless you use its native file
format, which has proprietary dependencies, you lose a lot of editing
abilities.
This means it is OK if Illustrator expects
certain aspects in a PDF to be present in a certain way so that it can
deal with them. BTW - there are a couple of PDF features that
Illustrator
cannot read properly. Nevertheless this doesn;t mean Illustrator is
broken or buggy, as it doesn't claim to be a PDF editing application in
the first place.
Then it shouldn't allow a user to open a PDF dropped onto the
application dock icon, without so much as a warning that important
metadata is being discarded.
In the case of your spool PDF files my guess is that Illustrator uses
the
Default color space mechanism for characterizing the document color
space
whereas Quartz just puts the needed ICC profiles into the PDF using
some
other way.
BTW - a PDF may have any number of ICC profiles, not just one. PDF is
not
an image format, it is a page description format, and each object on
the
page can have its own color space and ICC profile.
That the profiles are identifiable by Acrobat 6 and 7, as well as
Pitstop Pro means they should be identifiable by Illustrator. And when
there are mixed color spaces, Illustrator would be expected to either
ignore the embedded profiles if the CM policy is Off and assume Working
Spaces (and convert if necessary); or it would normalize to the
document's assigned profile (or Working Space if none).
