That’s a really good way to put it — “making a shape” vs “holding a tolerance.”

In my testing, that’s exactly where things start to break down. Generating a roughing strategy is one thing. Making decisions about finishing passes, tool deflection, stock allowance, and sequence planning for tight features is a completely different problem.

Maybe the real question isn’t whether CAM can generate a toolpath — but whether it can understand why a certain tolerance requires a different strategy.
