They do in on purpose, since the standard for Exif does not allow AdobeRGB: "While the EXIF header in your images does have a field called "color space", use of this data is very limited because the only two values allowed in the EXIF color space field are (1) sRGB and (2) unspecified." Anyway, it would be good if graphics programs try to identify also the known maker notes to find out the colour space.
