This proposal has been declined in the Neutron drivers meeting (see meeting logs). The change of the current behaviour of the API is not needed to fix LP#2016198 and could be in use now.
The proposal to fix LP#2016198 is to limit the creation of the "L3HARouterNetwork" DB resource [1][2]. The HA network is created per project. Only one network should be created at once. If we limit in the DB engine the number of "L3HARouterNetwork" per project, by making the "project_id" unique, we'll prevent the race condition.
