Yes, they implement of-proto providers. I guess we've seen a disjoint set of switches, which is not necessarily surprising :-).
What's the expectation for e.g. a P4 switch? It seems the most natural mapping is an OpenFlow-style pipeline (versus dpif). Admittedly, there are many other OpenFlow agents beside OVS (e.g. the P4 OpenFlow agent, etc etc), it just seems OVS is particularly important in open source networking (especially data center) and maintaining a distinct OpenFlow layer beneficial. That said, of course I wouldn't arm wrestle you over it if nobody else cares :-).
