 Good question. The reason is that not everyone needs this functionality, and not everyone is using 🏁 React Final Form with the DOM (e.g. some people use it with React Native). Therefore it makes sense to make this a separate package. This version of `Field` is a thin wrapper over the official `Field` component, and the only `Field` API that this library uses/overrides is the field-level [`validate` prop](https://github.com/final-form/react-final-form#validate-value-any-allvalues-object--any), so even if you are using this library's `Field` component, you will still get improvements as features are added to the 🏁 React Final Form library in the future.
