Hi, Daniel. I don't think this is a bad approach. However, at the moment, Han's work is with ovn-controller and ddlog is with ovn-northd. We've talked about using ddlog in ovn-controller, but there's been no work in that direction yet. At this point, I think Han's patches should be evaluated on their own merits and not held back for ddlog. (Unless someone is looking to run with it. :-) )
