There are three schools of thought on that:
1. SLAAC is the optimal way to configure IP addresses under IPv6.
DHCPv6 should only facilitate configuration of other things that SLAAC
doesn't deal with (e.g. DNS resolver)
2. SLAAC was a clever idea that for a variety of reasons (e.g. the
server configuration knowledge leak) isn't panning out. DHCPv6 should
replace SLAAC. It should do the same work as IPv4 DHCP, as expected by
folks used to IPv4.
3. Give it to me both ways. I'll make the choice I decide is optimal
for my network.
With my operations hat on, I'm a fan of option #3. I find the
theorists' intrusion into my prerogative as a system administrator
(option #1) to be disagreeable.
