 This option is useful if there is a bug in a native implementation, or a combination of a non-supported feature + a supported one doesn't work.
 
 For example, Node 4 supports native classes but not spread. If `super` is used with a spread argument, then the `@babel/plugin-transform-classes` transform needs to be `include`d, as it is not possible to transpile a spread with `super` otherwise.
