This approach is neither ideal or the simpler option.  Especially when DHCP can no longer be relied upon as being relied upon.  Some systems may ignore RA recommendations for stateful Address configuration, especial for devices that do not support DHCPv6.

There are already systems in IPv4 that ignore systems that are using addresses they weren't issued by the DHCP server. I see no reason such a system could not be put in place for IPv6 as well.
