RFC: `useKey` for resetting state as an alternative to the `key` prop
Summary
React has a special prop called key that is used to distinguish between rendered instances of a component within the same parent. It's essential for mapping a data array to a component array.
The key prop also has an application outside of mapped components. It can be used to force a component to re-render by changing the key prop value. This is useful when you want to reset the state of a component or trigger a re-render without changing the component's props.
This technique is described in You Might Not Need an Effect.
However, writing code where the parent is responsible for the state reset is somewhat of a "tail wagging the dog" situation, as often the component itself is the one that knows best when it needs to reset its state. This RFC proposes to allow components to use the key prop behavior in a more flexible way, enabling them to control their own re-rendering behavior by introducing a new hook called useKey.
