Hosnieh, Please see http://tools.ietf.org/html/draft-ietf-6man-ug-01 whose WG Last Call just ended, with a few comments to be incorporated.
IMHO, since we seem to agree that these bits have no defined semantics in an IID, you can specify them as you want in a new IID format. I would only suggest paying attention to the last paragraph of section 3: "To the extent that each method of IID creation specifies the values of the "u" and "g" bits, and that each new method is carefully designed in the light of its predecessors, these bits tend to reduce the chances of duplicate IIDs."
