Can you explain why that effort is more significant if a flow API
added first? I'm not saying it is easy to offload the existing
forwarding path, otherwise it would have been done already, but
I don't understand how the proposal makes this any more difficult.

Wait... I don't want to use OpenFlow to configure my laptop ;-)
We should leave the controller out of this discussion though. A
controller is not required to run OVS at all. OpenStack Neutron
is a very good example for that. There are even applications which
use the OVS kernel datapath but not the OVS user space portion.
We have a wide set of APIs serving different purposes and need to
account for all of them. I'm as much interested in an offloaded
nftables and tc command as you.
