-There are two configurations for consumption, both of which are packaged together as the default export. *Or they can be selectively extended &mdash; but when doing this, the pathnames [can't be written shorthand](https://eslint.org/docs/developer-guide/shareable-configs#sharing-multiple-configs).*
