@qmonmert : are you sure that this rule should be enabled?

See https://github.com/jsx-eslint/eslint-plugin-react/blob/master/docs/rules/react-in-jsx-scope.md

If you are using the new JSX transform from React 17, you should disable this rule by extending react/jsx-runtime in your eslint config (add "plugin:react/jsx-runtime" to "extends").

@murdos I see that it is what we do on the JH generator, but maybe it's not a good idea
