Are you submitting a bug report or a feature request?

feature request (or more like a performance request)

What is the current behavior?

onBlur, onChange and onFocus from useForm(...).input do not maintain referential equality between renders. Therefore React.memo is hard to correctly implement.

What is the expected behavior?

Preferably the aforementioned functions (onBlur, onChange and onFocus) would be referentially equal between renders.

What's your environment?

"react-dom": "16.8.2"
"final-form": "^4.11.1"
"react-final-form-hooks": "^1.0.0"
