That is true, but when considering a Neutron backend for OpenStack
deployments, people choose a subset of OpenDaylight projects and the
end result is a solution that is comparable in scope and feature set.
There are objective differences in where the projects are in their
lifetime, the HA architecture, the project's consistency model between
the neutron-server process and the backend, the development velocity,
the community size and the release model.
