Indeed. Before the first test flight, I was skeptical whether they can control the aerodynamic flight with those flaps. While they demonstrated their capabilities to control a rocket with the engines with the F9. But the one thing that seems to be rock stable is the aerodynamic control in the belly-down flight phase. The only issues were with the soft landing phase and that was related to fuel and engine problems. So I am absolutely not worried that SpaceX is going to figure that out soon. For me, there is only one big thing left to show: whether a starship with heat tiling can withstand the reentry.
