Documentation about Keys beyond usage in lists

The You Probably Don't Need Derived State post shows a pattern that uses the key prop to reset (force remount) elements in order to restart the component lifecycle: https://reactjs.org/blog/2018/06/07/you-probably-dont-need-derived-state.html#recommendation-fully-uncontrolled-component-with-a-key

It would be good to expand on that example in the main docs and discuss some of the pitfalls of that approach (for example, if a component is not written to account for changing data sources, the consumer must add a key to correctly reset the component).

Comece com a publicação vinculada “You Probably Don’t Need Derived State” e seu exemplo de componente totalmente não controlado com uma key. Atualize a seção principal relevante da documentação do React com um exemplo comparável e explique o comportamento de redefinição e as armadilhas relacionadas à alteração das fontes de dados; considera-se concluído quando o uso e as ressalvas estiverem claros para os leitores.
