(Get the code!)
Of course there's nothing wrong with 3 nodes as a starting point in many contexts. It's highly contextual though; as always with HA, the devil is in the details, so I'm not sure how much value there is in trying to make generalizations.
Nevertheless I agree with the goal of picking a commonly used, minimal reference architecture for HA of the OpenStack control plane, and documenting it as a starting point for consumers. If some distros don't easily support starting with 2 nodes, or have other reasons for needing to avoid that, I'm fine with accommodating them and picking 3 nodes as the size of the minimal reference architecture to document.
