No, actually moving useState to the custom component will still cause multiple rerenders in that component. Put a console.log in the custom component and see. The best way to avoid multiple rerenders is to useRef (or react-hook-form, if you're on Caffeine), since you're not doing anything with the value "as the user types" rather when the user is done typing.
