The counter argument probably being that rather than having two
alternate autoconf mechanisms, we have two mandatory autoconf
mechanisms, since non of the can provide all the encessary information
needed for autoconf (e.g., one doesn't provide EDNSS, while the other
does not provide default routes).
Unfortunately, religious wars about SLAAC vs. DHCPv6 didn't help us at all.
