[`eslint-config-react-app`]: consider configuring `react/no-unstable-nested-components` rule?

[karlhorky]

Is your proposal related to a problem?

Components nested inside components without memoization leads to unstable components (the nested component and all its children are recreated during each re-render). eslint-config-react-app could warn or error upon seeing this pattern.

Describe the solution you'd like

eslint-config-react-app could configure the new react/no-unstable-nested-components rule that will be released in eslint-plugin-react@7.23.0 (see pull request and changelog)

Describe alternatives you've considered

Do not lint for this problem
