Does the React plugin not support React 16? I couldn't find related documentation.

Describe the bug

It seems that 1.0.0 already uses the JSX runtime. Does this mean that support for React 16 has been abandoned?

Reproduction

Yeah I should document it. This plugin only make sense if your version of React support Fast Refresh, which means >= 16.9 IIRC.
JSX runtime was introduced in 17 IIRC, with this plugin you can get back to default JSX transform with jsxRuntime option.

I'll keep this one open and update the Readme next time I do a change
