IPv6 routers are the central servers for SLAAC with the
complexity of setting up.

Moreover, SLAAC is stateful in the worst way, because states
of address assignments are held unnecessarily distributed way,
which is why time and power consuming DAD is considered to be
necessary.

Just as most, if not all, NAT boxes have preconfigured DHCPv4
service to offer part of preconfigured private address
space, home IPv6 routers may have preconfigured DHCPv6
service to offer part of configured public address space.
