Civ 6 seems like a game where it would have been good for them to add hooks for people to add their own AIs easily.

I suspect the built in AI does okay if you place units in a limited area (which is likely how they tested it), but it struggles getting armies around the full game map with complex borders.

In my experience, the Civ 6 AI doesn't do combat well in limited areas either. And it hardly ever uses planes and bombers. I really hope Civ 7 will be focused on AI innovations.

There are mods already that improve the AI. So it is feasible.

Yes, but there are severe limits as the DLL is a black box. They can only tweak the inputs.
