Autofill many times fill data in wrong fields, and it break UI style too.
For me, Chrome has countless times clobbered the context-aware autofill (address fields, countries etc.) provided by the website with their useless autofill overlays.
I would much prefer if I could all together disable Chrome's suggestions in DOM input fields. Even when it has nothing to autofill, it sometimes puts something in there to take me to autofill settings or something.
