It would be cool if you could define certain aliens as using sneaky AI in the rulesets instead of all or none. Would add a lot of variety and would be great for modding. Sneaky AI sounds perfect for Sectoids but aweful for Mutons. Would be super awesome if it was defineable per rank as well. Maybe you don't think Floaters in general should be sneaky, but you want their Leaders and Commanders to be sneaky to avoid being killed. Could add so much!
