We definitely need DHCPv6 relay as some ISP only provides a /64 prefix, where relay is the only way to grant IPv6 accesses to LAN devices.
By default, OpenWrt uses dnsmasq for IPv4 DHCP and odhcpd-ipv6only for IPv6 DHCP. The DHCPv6 relay (powered by odhcpd-ipv6only) works as expected and we only need to change /etc/config/dhcp to be like this to make it work:
If one uses dnsmasq-full to handle DHCP for both IPv4 and IPv6(opkg remove dnsmasq odhcpd-ipv6only and opkg install dnsmasq-full), the DHCPv6 relay stops working. The /etc/init.d/dnsmasq script does not seem to generate dnsmasq configurations for these IPv6 options:
Confirmed on OpenWrt 23.05.3 x86-64.
