As they aren't today and IMO having e.g. both "Openvswitch" and "ML2 - Openvswitch" options in the same question may be confusing as well.

It's maybe not that critical for developers but IMO it would be good to see how many users are using "default" ML2 plugin and how many are using some custom, 3rd party implementations of Neutron.
