Maybe I misunderstood the scope of your question. The ipAddressOrigin TC supports 4293 the same way it does 3041. The commentary in the RFC was written prior to the elevation of privacy addresses to draft standard. My understanding of 4293 is that it is not meant as a mechanism to control the generation of privacy addresses in any way. I am not aware of any *standardized* method for doing this. Though section 3.6 of 491 encourages vendors to provide such a knob.
