Dubious?  Perhaps.  I don't know of any specification that suggests sending an Information-request message upon receipt of information about a new prefix or prefixes.

Expensive?  Can you prove "expensive"?  In my opinion and experience, this claim is more FUD about how "expensive" DHCPv6 is.

Way off course for this discussion?  Almost certainly.
