https://github.com/davidmarkclements/v8-perf https://github.com/davidmarkclements/v8-perf the performance consideration seems like a strawman for any non critical code path. The bottom section of the React page linked in the last bullet point https://reactjs.org/docs/hooks-intro.html#gradual-adoption-strategy https://reactjs.org/docs/hooks-intro.html#gradual-adoption-s... contains this: "we will keep supporting class components for the foreseeable future. At Facebook, we have tens of thousands of components written as classes, and we have absolutely no plans to rewrite them.". The Google JS Style Guide also seems quite content with ES6 classes. Plus, the article goes on to pose completely different alternatives to the class keyword than what is used in React.
