I may not be clear on the original post's "intent" but when placing RGB
images saved from Photoshop *with* AdobeRGB (or any other profile) as the
embedded profile into a blank InDesign page, the embedded profile remains
the same.
This correctly shows up in the Info palette and under Object > Graphics >
Image profile.
Alt-clicking the placed image correctly opens up the image in Photoshop with
the correct profile assigned.
Nothing appears broken to me in this chain :(

Update: retrieving trustworthy colorspace information from Exif data seems
to be even more fragile than I expected. See
<http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/EXIF.html>:
--------8<--------
*ColorSpace*
1 = sRGB
2 = Adobe RGB
65535 = Uncalibrated
(the value of 2 is not standard EXIF. Instead, an Adobe RGB image is
indicated by "Uncalibrated" with an InteropIndex of "R03")
*InteropIndex*
'R03' = R03 - DCF option file (Adobe RGB) 'R98' = R98 - DCF basic file
(sRGB) 'THM' = THM - DCF thumbnail file
-------->8--------
... so maybe Adobe should consider to ignore the Exif ColorSpace tag by
default also in Photoshop in future releases. This way there is at least
consistency across all CS applications. The other way to accomplish
consistency would be to make *all* CS applications aware of Exif ColorSpace
informations and to synchronize the setting weather to honor or ignore them
with Bridge's Color Settings files.
