Unfortunately, it seems to be the case. Just saw there is a summit talk about it called IPv6 Feature in Openstack Juno. Dual stack floating ip support is planned in K. However, I couldn't even get single IPv6 floating IP to work. Even though I configured only IPv6 subnet for the external network, I got those errors from neutron-l3-agent when associating the floating IP to instance.
