Warn if using ES6 class but not directly extending React.Component

Now that React 16.x is taking out createClass, is there currently a way to warn if not directly extending React.(Pure)?Component. That was always my issue with ES6 classes (Button inherits Tooltip, Tooltip inherits onHoverComponent, etc.) and have been holding off on them. I’m seeing isExplicitComponent in the utils module which I believe would do this, if surfaced.

Maybe it would be an additional feature to prefer-es6-class rule:

'react/prefer-es6-class': [1, 'explicit'],

Anyone else think this is a good idea in order to promote use of higher order components for composition over classical inheritance? This would be in line with @gaearon 's How to Use Classes and Sleep at Night

In react, inheriting from something that’s not React.Component or React.PureComponent is a long-ago-decided antipattern.

If you do it anyways, you can stick /** @extends React.Component */ before the class, and this plugin will pretend it’s a react component.

I believe it’s undocumented atm, and uses jsdoc syntax.
