Hello Lassi,
You have expressed exactly the reason for mandating "route optimization". It's because a node that does not handle the Binding Update causes remote nodes to do extra work with no noticeable local effects. It's for the overall health of the IPv6 Internet that nodes should be required to implement Binding Update and along with it the lightweight Return Routability tests. Regards, Charlie P.
