When IPv6 routing is enabled (net.ipv6.conf.*.forwarding), autoconfiguration is automatically prevented due to that RFC, regardless of the net.ipv6.conf.*.autoconf value. OpenWrt should be configured as an IPv6 router by default, as per the way it's configured as an IPv4 router by default (IPv4 forwarding is enabled by default in /etc/sysctl.conf - net.ipv4.ip_forward=1). Therefore I believe that the /etc/sysctl.conf file should have net.ipv6.conf.all.forwarding=1 set by default. Right now it's in the file but commented out (since r12351). Does anyone know if having it in there by default causes any errors if kmod-ipv6 isn't installed? If someone decides not to use their device as a router, all they would need to do is modify the /etc/sysctl.conf file to disable IPv6 forwarding, and autoconfiguration would spring back to life.
