What do you disagree with? I was pointing out that using Linux bridge will
not reduce the complexity of the model of self-service networking, which is
what the quote was complaining about.

I just wanted to point out that one of the 'major disconnects' as I
understand it will not get any better by switching drivers.

I disagree. Complexity for the operator includes more than the API.
It also includes troubleshooting what just went wrong when your
network decided to do a headstand. As a datapoint, compare the ease
of connecting tcpdump to a bridge interface vs the ease of
connecting tcpdump to an OVS instance.
