Like I said before, that would pollute the network with many multicasts which can seriously degrade wifi

Huh?  This is no worse than IPv4 where a host comes up and sends a
subnet-broadcast to get DHCP.

The IPv4 host does this once and gets its lease. If there is no DHCPv6 server then DHCPv6 clients would keep 
broadcasting forever. Not a good thing.


Which is no worse than the behavior of an IPv4 host on a network without a DHCP server.
