Micro is often written off as a mechanical task, but this is only relevant with expert systems (like microbots). There is a lot of tactical nuance and understanding that comes in micro, for a neural network/learning algorithm to understand and optimize is actually very impressive just as much as macro. Knowing it's optimal to blink when your shield runs out before taking hull damage? To dance your weakened stalker to bait your opponent to overextend? To focus fire but not overkill? To wait for a projectile to be mid-air before blinking or picking in a transport? There's so much more to micro than precision and APM. To your other points, SC maps have lots of ramps and cliffs and high-ground/low-ground impact (no bonuses, but vision constraints and battle surface area and choke points) AI development is not easier because of micro potential, because it means the AI needs to be prepared to deal with a wider range of effectiveness for any given unit or set of units, they won't always scale linearly in impactfulness or between different player's playstyles
