I would like to propose a third option. Create a design team in nvo3 to come up with the goal of proposing one data plane protocol that consolidates the best features of the three. Outside of extensibility there is fundamentally little difference amongst these, and the different models of extensibility (flag-fields, TLVs, NSH) could be fit into one protocol. Also, the encapsulation design considerations (draft-ietf-rtgwg-dt-encap-01) provides a good reference for creating such an encapsulation protocol.
