Yeah I can even imagine a thriving "marketplace" for specialty code that top players would keep secret.

And it doesn't have to just be for micro. For people who are bad at macro, maybe code can be written to consistently maintain X workers at all bases.

The difficult part here would be how to balance the AI-assistance. Is lines of code (or number of characters) a good proxy for complexity? What's the number-of-character to benefit ratio?

I guess that's ultimately determined by the individual player's strengths and weaknesses. If a player sucks at macro, then the macro script is worth the number of characters.
