Building really good complex form widgets is hard work. You have to handle ARIA/accessibility, ensure you have support for focus and tabbing, handle lots of keyboard shortcuts as appropriate, etc. Solid implementations of autosuggest inputs, token input fields, or fast scrolling tables can run into the thousands of lines. Having reusable versions of them would be very helpful for the React ecosystem.
