I think the Ukrainian Stugna & other ATGMs (not only with soviet heritage) use the rotation trick - you get some stabilization for free, might need less control surfaces and maybe even simpler sensors. IIRC in the Stugna case, they even use solid fuel micro motors - they have a couple dozen of them in a rignt near the nose and fire them as the missile rotates in flight providing a kick in the right direction to hit the target. Given the missile usually flies for <30 seconds, this is perfectly adequate versus a complex set of aerodynamic actuators.
