Well that’s wild because I had a disagreement with beziers recently and did a similar thing! [1] albeit with more madness and less polish. Driven by the a/s/d/f keys with find edges snap to reference images and curve fitting to construction geometry.
Feel I should also call out Freyr’s videos for anyone who has missed them - continuity of splines [2] and the beauty of Bézier curves [3]
