Are you saying that IPv6 allows for in the network header insertion/removal? If so, please tell me how AH, Path-MTU Discovery, and ICMPv6 error reporting works -- all very basic functions of IPv6. IPv6 is an end to end protocol. With RH you change the DA on the flight, because routing only works based on the DA -- there's no other way to specify waypoints. If you claim otherwise, that can be, at best, a major misunderstanding of how IPv6 works.
