It's true that they still can't really just go code the decisions themselves (nor do they want to) but they can and are put in a position to maintain, add, remove and change the rules in the decisions. It takes more than just exposing the logic as rules, though, as I have noted before.

Many a time the business is afraid (read risk averse) about touching legacy systems because the business rules are not explicit and not enough transparency exists in order for code to be modified to accommodate new business requirements I think business rule automation via decision service is also relevant for decomposing business logic/rules embedded in legacy systems.

Writing business rules may be easier than traditional programming, but this is still a programming task. Otherwise we wind up with the same kind of flawed logic that we see in spreadsheets; academics have shown how often spreadsheets have fatal flaws despite the firm believe that they are correct. The fifth point (of your four?) is fine so long as we understand the rule writer is still an engineer.
