You are right about that. I even saw this when experimenting with the feature this morning but somehow it slipped my mind again before I wrote it down, so it’s good you added it.
But still. there is no first rate: “Draw arc track” in the menu. circular tracks are only made as a “fillet” feature in corners. This is still far from ideal when your project relies on circular tracks. Take for example this old post (too old for KiCad V6)
