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

I have never found an IPv6 router--with SLAAC enabled--any harder or
more complex to configure than an IPv4 router.  You need to route IPv6
anyway.

The only time you need to perform extra steps is when you want to run
DHCPv6.  You need to enable the M and/or O flags and turn off the
'autonomous' flag (if you don't want a host to get both SLAAC addresses
and DHCPv6 addresses.  Then you need to turn on relaying unless you are
putting the DHCPv6 server on the same wire.

We need to make it easier to run DHCPv6, not harder to run SLAAC.
