I see your point. I’d challenge Microsoft to show a legitimate use case or scrap that feature. Their must be something there. Maybe they are leaving the door open for some business automation? (No shit, right?) It seams to me that some of Microsoft’s ideas include looking at applications already out there and thinking of ways to allow their products to do the same thing. So Enterprise Microsoft Customers can automate processes in a way that lets them avoid licensing other software. Usually its probably more a pain in the ass and takes a lot of time to find a way to automate everything using Microsoft Office, but if the stars align (Engineers with some down time, and the end project wont be frustrating) it could be worth it to keep the option open.

Have you heard of many stories of this being exploited in the wild? Why not just disable Macros with Group Policy?
